Treating Your Water with Magnets

Water comes in two forms, hard and soft. The difference between these two types of water is the mineral content. Hard water contains a larger amount of mineral deposits compared to soft water. The hardness or softness of water is actually measured by the content of calcium carbonate in it. This is expressed in relation to a specific volume of water. Units used are grains per gallon (gpg), parts per million (pmm) or milligrams per liter (mg/L).

Hard water is usually converted into soft water in households. This is because it is known to leave some deposits of calcium in the pipes thus messing with the plumbing. Pipes can get clogged and the amount of water passing through them reduces with time. Faucets, dishwashers, shower heads and heating elements in water heaters can get clogged as well. Heating efficiency is reduced as a result and the water leaves marks on dishes. Working soap into good foam becomes a little more difficult as well.

Conventional water softening

The regular and common method used to soften water is a process that entails removing magnesium and calcium from water and replacing them with sodium. This makes it softer and therefore reduces the scale that is calcium deposits. This can be described as an ion-exchange process. Water softeners can easily be found in stores locally.

This procedure however comes with a few disadvantages.

·   Soft water takes a much longer time to remove soap. This will leave a slippery feeling on your hands.

·  Increased sodium intake is not that good for your health. How much you take in will be determined by the amount of water that you drink and how hard your water is. You can opt for a separate tap that you can use for hard water which can be used for drinking water only.

·  You will need to frequently add salt to this system.

·  Sodium causes corrosion on the inside of the pipes while calcium deposits seem to prevent corrosion.

· This softening system will often require a regeneration process. This is where the magnesium and calcium that was removed is completely washed out and the water dumped down the drain. Some water will definitely be wasted but the amount depends on how much water is softened.

· Soft water tastes a little different and others may not like it.

Magnetic water treatment

Two strong neodymium magnets are placed on either side of a pipe that holds incoming hard water. Neodymium magnets have a very strong magnetic field and this goes through the water. No calcium is taken out in this procedure but a change occurs in the calcium.

The change is only visible with an electron microscope but with time you should see a difference with your naked eye. Passing hard water through a strong magnetic field changes the structure of the calcium deposits. In hard water the calcium deposits are known as calcite and these have small beads and clings onto surfaces. Magnetically treated water forms deposits of aragonite, which is a form of calcium that has longer strips and is less likely to cling to surfaces and form scale.

Coercivity and the Horseshoe

Magnets have been in use for ages and currently the shape that is most recognized and is used to represent magnets is the horseshoe. Why is it that magnet are usually made in this shape and why does it provide an advantage over the other shapes?

Many people say that magnets are designed like horseshoes because putting two poles together brings about much greater force and this increases the strength of the magnet’s hold. This is true but it may not be the only reason. You can still be able to put two poles together if you place two magnets side by side. Think about the horseshoe and specifically the circular part. This part does not get used and may be viewed as extra material. This therefore disqualifies this theory as being the only reason for the horseshoe shape being used in magnets.

Coercivity

A magnet is usually considered strong depending on the pull force experienced when it is in use. A magnet’s strength can also be measured by finding out the magnetic field strength that will be able to demagnetize it. This is what is known as coercivity.

 Earlier magnets had such a low coercivity that their own magnetic fields were able to demagnetize them. These magnets were mostly made of iron. More powerful magnets have been developed over time and this includes an increase in coercivity as well. Neodymium magnets are stronger than most magnets and they also have a higher coercivity and this allows them to maintain their magnetism over time.

Significance of the horseshoe shape

The shape of a magnet influences how much magnetization is lost. A long cylindrical magnet will stay magnetized longer compared to a thin disc magnet. It takes a little more to demagnetize a horseshoe because it is like a stretched version of a cylindrical magnet.

The permeance coefficient (Pc) of a magnet is defined as how difficult it is for a magnet’s field lines to move from the north pole to the South Pole. This means that taller magnets will have a higher Pc and shorter magnets a lower Pc. A horseshoe has a high Pc as well. This prevents it from easily getting demagnetized. This is further increased by using a steel keeper.

This explains why neodymium magnets are not made into the horseshoe shape. Neodymium is a very strong magnet that does not demagnetize at all. In the event that a neodymium magnet gets demagnetized, you will find that the magnet was probably very thin or it was exposed to very high temperatures.

You can even place two neodymium magnets together without causing them to demagnetize each other. Their coercivity is very high which makes them more flexible for use in different applications. Neodymium is also a hard and brittle material. Shaping it into horseshoes would cause them to break very easily.

This shape is therefore applied to magnets with low coercivity like Alnico and iron. They will be able to keep their magnetization for longer with this shape.

Significance of A Disc Magnet

The hard drive is like the brain of the computer. It is responsible for storing all the data and information. Disc magnets work well in storing the data in the hard drive of a computer. Through the use of Disc magnets you can easily write to the drive, store data and can very well read the data on the hard drive. The transfer and erase of data using Disc magnets is very easy. Storing and retrieval of data through a magnetic mechanism is more simple and reliable. It can store data for over the years without any damage. While in case if for any reason the hard drive no longer works, even then you can able to recover your stored data through removing the magnet from the hard drive. The hard drive stores all the information in it and can retrieve whenever needed.

If you get into the mechanism of a hard drive, you will find it is just made up of a several different parts; those are electrical board, the plotter and a head. The disc magnet gets regulated by this electrical board. The plotters are responsible to store information. These are the aluminium or glass discs coated with a magnetized material to store and record data. It has been seen a few computers use more than one plotter as it can store huge data in less space.

While if for any good reason the hard drive stop working and fails to store and retrieve data from its memory, you can easily remove the magnet from the non working dead drive. You can able to get back your stored information through the help of the magnet, even when the hard drive doesn’t work. The plotter is attached to the magnets through screws and would be removed while removing the magnets. The magnets fixed with glue to the hard drive. When a a hard drive fails to work, the magnets are removed from the device. But if the hard drive is once opened, it cannot be used again. But the better part is that the data stored in the magnets of the hard drive can be recovered.

Many other electronics devices store information in the same way. If you will see the mechanism of video tapes and music cassette tapes you will find a great similarity in storing information. These magnets are not same like the disc magnets found on hard drives, but they are very powerful magnets and thus used in different significant purposes.

A Discovery of the rare-earth element

It is the amazing magnetic field which exists behind almost every technological device used for the modern commercial, industrial as well as household purposes. The rare earth elements used in the advanced motors, generators and computers to minimize the use of electric power is nothing but the earth magnets. It possesses the magnetic field similar to the permanent magnets. That means it is almost impossible for these magnets to demagnetize. Only heat is the core enemy of the magnet. A neodymium can lose its magnetic power in elevated heat. In fact the magnets are so strong and powerful because of the raw metal used to make them tremendously powerful.

The earths magnets are made of the material called ferromagnetic metals, which, when magnetized can generate a strong magnetic pull. This magnetic pull or magnetic field is responsible for the attraction of the metal. It is so powerful that it can crush your finger if it comes between two magnets. Often it can become the reason of serious health complications if swallowed by little children. So it is advisable to keep it away from the reach of the kids. Though magnets are the metal of fun, but children should not be allowed to play with it. A few preventive cautions are there which should be followed to safeguard you from the hazard of the metal. While handling big strong magnets it is wise to cover your eyes and hands with proper protection. Neodymium is a brittle metal so while machining there is a chance of breaking of the magnet and the tiny particles of the metal can fly in airs which are not less sharp than glass particles. These magnets can even break if dropped from the hand.

In the later years of 1900, Earth magnets were discovered. Since that day researches are going on to produce more and more strong magnets. The permanent magnets can be used for scientific, commercial, industrial and household applications. the Neodymium magnets are safe and affordable. That is the reason it is widely used by school children in their various science experiments. It has a wide usage in household application also. In the scientific community it can be used in the mechanism of self-powered flashlights, computers, cordless devices, in different electronic devices, refrigerator, washing machine, microwave and the like. All the electromagnetic devices rely on magnets for their function. Starting from the hard drive of a computer to the magnetic credit card, all functions with the power of magnets.

Types of Rare Earth Magnets

Magnets have been in existence for a very long time and magnet strength has increased as innovations and further research continues. A stronger magnetic material was developed in the 1900s and it has continued to be used in various industrial applications.

This material is composed of a combination of rare earth elements. Magnets derived from these materials are therefore known as rare earth magnets. They are the strongest magnets currently available, with their strength being significantly higher than all regular magnets. They may produce a magnetic field of about 1.4 teslas while other magnets produce about 0.5 to 1 tesla.

Rare earth metals are not really rare because their abundance may be similar to metals like lead or tin. These metals are naturally ferromagnetic. This means that they can be magnetized permanently but their natural magnetism is only visible below certain temperatures. When mixed with metals that possess magnetism at higher temperatures such as nickel, iron and cobalt they form quality compounds that make for good magnets.

Weak points

Their biggest weakness is that they are very brittle. They break very easily and can easily get corroded or chipped. They are therefore usually covered in a less brittle material like plastic to avoid constant damage from breakage or chipping.

Advantage

The atoms found in rare earth elements have been found to have a very high magnetic anisotropy. This refers to the ability of the particles to get easily magnetized in one direction but they resist magnetization in another direction.

Rare earth magnets are of two types, namely samarium-cobalt magnets and neodymium magnets. Of the two types, neodymium magnets are more common.

Samarium-cobalt (SmCo) magnets

These are the first type of rare earth magnets that were invented but they are not commonly used. This is due to the fact that they have a weaker magnetic strength and are more expensive. They are however used for applications that require a high magnetic field strength under high temperatures because their Curie temperature (the temperature at which it loses its magnetism) is higher.

Neodymium magnets

These are made of neodymium, iron and boron and may sometimes be referred to as NIB. They are the most affordable and strongest of rare earth magnets. Their application is mainly in devices that require strong permanent magnets for instance jewelry clasps, cordless tools and computer hard drives. They have to be coated to prevent corrosion.

 Ferrite magnets

These are made of compounds that are combinations of iron (III) oxide and ceramic materials. They are brittle, hard and normally non-conductive. There are hard and soft ferrite magnets.

AlNiCo

AlNiCo is actually an acronym that stands for aluminum, nickel and cobalt since these magnets are alloys of these three materials. You will sometimes find titanium and copper in them. They are highly resistant to losing magnetism, are ferromagnetic and are therefore used in the production of permanent magnets. They were actually the strongest magnets before rare earth magnets were developed in the 1970s. Their strength is only exceeded by rare earth magnets where more powerful magnets are required for industrial use.

Discover More about Rare Earth Magnets

Magnets have been in use for a very long time and they now take up a large chunk of every industry since they are used in most of the common and important technological devices that are found in households and industries alike.

The magnets that are used most are popularly known as earth magnets. They are very much like any other permanent magnet but the metal they are made from is what sets them apart. Rare earth magnets are made from metals that are ferromagnetic. Ferromagnetic metals are those that possess magnetic properties below a certain temperature even without the presence of an external magnetic field. These metals produce a very strong magnetic force when they are magnetized and this makes rare earth magnets very powerful.

The strength of a rare earth magnet is said to be so much to the extent that a finger placed between two magnets can easily be crushed. The magnet force they produce can also be harmful to the health of young children and babies if they happen to ingest them. It may at times even lead to death. They should therefore be kept away from children and should be handled carefully.

Most popular

Early magnets were discovered before the 18^th century but rare earth magnets were only developed later in the 1900s. They then became the magnet of choice for various uses. Of the two available rare earth magnets, neodymium is the most common. It is found in varying shapes and sizes.

Rare earth magnets were initially expensive but prices have gone down with time. Regular consumers can actually be able to buy them for use in their households or any other purpose.

Application  

This type of magnets is very common in electromagnetic devices like computer hard drives. They are also found in refrigerators, metal detectors, cordless items like microphones and even self-powered flashlights.

Their extra strong magnetic force has pushed along the phasing out of other weaker magnets but not completely. These magnets are however very brittle and can therefore break very easily if they fall. They should be handled carefully for this to be avoided.

You can get rare earth magnets according to your specific needs. If you need them in varying strengths, different sizes and shapes they will be customized to meet your exact specifications. A licensed manufacturer would give you good quality magnets since the sale of such magnets is controlled. Where you are not certain what design would work best for your project, the manufacturer would be able to help you design your own customized magnets for your project. 

Any magnetic data storage devices like computers and credit cards should be kept away from these magnets at all costs because they could easily be ruined. Such storage devices have their data stored in magnetic patterns. When a magnet passes over them, especially a strong one, the pattern gets scrambled and the data gets erased. Such strong magnets require very little time to erase data on such devices so be very careful around them.

Neodymium in everyday life

Do not get confused with Neodymium magnet and rare earth magnets. Both are different from each other.  Neodymium magnets are strong and cheap and used in wide ranges of applications. It has some distinct attributes that you won’t find in any other magnets. However it is the most general type of rare earth magnets that is useful for various household applications. The substance is strong enough to be used in various applications.

Neodymium magnets come in market in different shapes and grades. The quality of the magnet depends on its grades such as the N40, N35, N45, N42, N45, N50, N48, N52. A greater grade of magnet has a more magnetized field.

The most common use Neodymium magnets are for the purpose of cleaning up applications. It can be helpful to collect the spilled nails, staples or pin over the floor. If you just float a magnet over the surface you can easily able to pick all the fallen objects up.

Neodymium magnets can be used for storing and holding various essential household items. Important papers and notice can be placed over the fridge door using a piece of Neodymium magnets. Memorable photos and other documents can be stored with the help of this.  

Magnets can be helpful to keep the door closed. You can use it in drawers, doors and cabinets to keep it closed always. Two small magnet can be placed with one side attached to the inside panel of the drawer and other side to the door or drawer itself. Proper alignment of the magnet helps in keeping the draw shut.

Another most common application of magnets is to get a stuck battery out of its case. Often it happens that batteries get stubborn with its case. It becomes difficult to get it out from the toy or clock. However use of strong magnet can make the task easy for you. The strong magnetic power of the neo magnet helps the battery to pop out easily with no effort.

In the kitchen also there are lots of uses of these Neodymium magnets. You can use magnets in building a knife holder which can be very helpful to hold your entire knife at a single place for easy access and smart use. Thus instead of purchasing an expensive knife holder from the market you can design your own one through using a bar magnet. It will cost you less and can be made with different appealing designs to go with your home décor.

How Magnets are used in the Fridge

Most people are certain that the only magnets that are in contact with their fridge are those small ornamental fridge magnets that are sometimes used to hold up shopping lists and adorable photos of their children. This is however not true.

Your fridge door actually has a magnet inside it. The fridge is made of a metal and so when the magnet is placed there it attracts the metal in the fridge and the door closes smoothly.

Why the magnet

·         It becomes much easier to close the fridge door because there is minimal resistance from the weight of the door.

·         You will always be certain that the door is completely shut. This will save you a lot of money in temperature loss from an open door since it creates an airtight seal. It also ensures that your food cools properly making it last longer if it is stored in the right container.

What if it won’t close?

If your refrigerator door does not close any more it could be that the hinges are damaged or the rubber seal on it is faulty. The hinges can be tightened using a screwdriver if that is where the problem lies. If it is with the rubber seal then it needs to be replaced. You will know it is the rubber seal if you place a piece of paper on the door and then close the fridge door. Try pulling out the piece of paper and if it comes out with no resistance then the seal needs replacing.

You can also place your own magnets to make sure that your fridge door closes. Buy a few neodymium magnets from anywhere that is safe (you can get them online as well). An assortment of sizes may be best so that you have a variety to choose from. Once you get the magnets place them in the space between the outside of the fridge and the magnetic strips. Stack as many as you can until you find that your door closes with ease. It should not take very long and they will continue serving you for a long time.

How it came about

Old refrigerators did not have magnets in them. They just had a latch and that is what was used to close them shut. Just like any other electronic device newer models were introduced into the market and people discarded their old models.

Some would leave their fridges on their lawns but children would come playing in that area. Some children found these fridges a perfect place to hide during a game but they did not know that once the fridge was latched from outside it became airtight. There was also no way of unlocking it from inside. There were a number of incidences where children suffocated in disposed fridges while playing and people began a movement to make fridges safer. That is how magnets found their presence in fridges.

This method has proven to be very useful because small children cannot easily open fridge doors thus keeping it safe. Food also does not go bad fast.

Prerequisite of Neodymium Magnets

A detailed investigation about the physical and thermal attributes of the strong neodymium magnetic materials gives the following specification.

Magnetic Plating or Coating:

Neodymium magnets are the strongest magnets among all mother kinds of magnets available in the market. It is a composition of the metal Iron, Neodymium and Boron in a specific proportion. The iron element of the magnet may cause rust over the period of time if exposed to the open environment. So in order to strengthen the brittle magnet material and to protect it from corrosion, plating or coating over the magnet is a best option. A lot of coated materials are there for which are widely used for coating a magnet. However the best option among all is the nickel platting. The technique of nickel platting is a process of triple plated coating. The three layer coating comprises of separate coating of nickel, copper, and nickel again. This repeated three layer coating make the metal strong and durable enough as compared to single nickel plated magnets. Even you will find the gold plated magnets with quadruple coated with nickel, copper, and then nickel again with a final top coating of gold.

Machining:

Neodymium magnets are brittle in nature. So there is a risk of getting it break into pieces while doing machining on them. The material is however more likely to chipping and cracking, that is the reason why it is not suitable for normal machining. The machining process generate heat, which may cause the neodymium demagnetize its magnetic field. Thus machining of this magnet is not advisable.  

Demagnetization:

Rare Earth Neodymium magnets possess a great capacity of high resistance to demagnetization. Neo magnets are permanent in nature that means it almost won’t lose their magnetization even if it is dropped. However the risk of losing the strength of the magnet lies when it is heated over a maximum operating temperature of 176°F (80°C). This may be the reason of a complete demagnetization of the N grades magnet.

Strength:

If you are a novice in the field of handling a neodymium magnet, then be careful in your act. Follow all the safety cautions before dealing with the magnet. Always cover your hands and protect your eyes through gloves and goggles respectively in order to keep yourself protected from the hazards of the metal. Magnets have an amazed strength. So if it breaks down into tiny sharp particles, then the magnet particles will fly in the air and can get into your eyes. Those sharp particles are not less harmful than glass particles.

A Lesson about Magnetic Separation

As we all know magnet act through its magnetic field. It can be assembled in order to execute some significant magnetic separation applications. Magnets through its intense magnetic force attract the metal like steel, iron and other ferromagnetic bits. Thus, while doing the separation activities it can easily separate contaminants out of other materials mix. However it is a fun element while seeing the use of magnet in this way. But at the same time it is significantly useful as well.

When we talk about a magnetic separator a question always come to our mind. We know very well that magnet attacks iron and sticks to it. But what will we do when we have to use magnets to separate the metals of non- ferromagnetic in nature. That means how we separate a mixture of metal when none of the element of the mixture is sticking to magnet. For example can we separate aluminium which is not a ferromagnetic metal from other non-metallic trash?

We can easily separate the ferromagnetic metal from another materials mix. For this we have to construct a conveyor belt attached with two magnets on both the side, which can provide a strong magnetic hold to execute the task. Thus while the material mix come with the contact of magnet the non-ferromagnetic stuff which is not attracted to magnets separated automatically by just falls straight down. The technique is quite useful for separating ferromagnetic materials such as nickel, iron or steel from other materials.

But the main drawback is that magnet does not stick to the non-ferromagnetic metals like aluminium or copper, as well as many other electrically conductive metals. So how can we use the magnets to separate these materials from other stuff?

Fortunately science has the solution for that also. The key to solve the issue lies with Eddy Current. Eddy Current enables the magnet to spin at a greater speed in that conveyor belt and the technique will work with the repelling force between the magnet and the metal. Here the magnets exert a force on the metal resulting it throwing off out of the stuff rather than just dropping them. Thus the metal of aluminium or copper which are of non-ferromagnetic in nature can get separated from the stuff. Thus magnets are useful in the magnetic separation applications for both ferromagnetic as well as non-ferromagnetic stuff.

Some New Applications of Neodymium Magnets

Thanks to the latest researches, today we are aware of even the most unexpected yet important uses of magnets in industries and in our daily life. In reality, we are completely surrounded by science and technology such that there are no limits to new applications of the available resources. This is applicable in case of neodymium magnets as well. As already known, these magnets belong to the group of rare-earth magnets and are the strongest ones available in the market. Since the invention of neodymium magnets in 1982, much advancement has taken place. Consequently, we have some amazing applications and facts about these magnets which can prove revolutionary for many industries and even some aspects of our daily life.

It is something quite obvious that neodymium magnets, being the strongest of all, can be used in almost all the known cases where magnetic field is required. They can replace other types of magnets and perform the required function very well. Such applications include electric generators, motors, door locks, speakers and computer hard disks. However, being relevant to our topic, we will focus more on those applications which are inspired from the availability of neodymium magnets. Their extra-ordinary strong magnetic field has led to some new developments which were not very likely before.

·         Neodymium Magnet Toys

These magnets toys are marketed in the form of spheres which are joined together to from different 3D structures. Neodymium magnet toys are also referred as children building set and in some cases, these are used for education purposes also. Strong neodymium magnet spheres are also ideal for conducting research and experiments in school labs.

·         Use in Sports Parachute Equipment

Parachuting is an increasingly popular sport, but risks of injury are a bit high. Regarding that, neodymium magnets are used in sports parachute equipment. This makes it easy to open and close the parachute reducing the risk of injury.

·         Magnetic Resonance Imaging (MRI) Scanners

This is perhaps the most interesting application of neodymium magnets in medical. MRI scanner is somewhat the latest technology in medicine which is used to scan the body for tumors and other similar health issues.

·         Surgical Linx Anti-reflux system

This is another application of neodymium magnets in medical. Linx anti-reflux system is actually a treatment of gastroesophageal reflux disease (GERD). Neodymium magnets are surgically placed in the lower esophageal sphincter to cure this disease.

·         Maglev Trains

This exciting application of neodymium magnets is not known widely. Maglev is floating train where neodymium magnets are used to repel train engine from the track. This ensures a frictionless circulation. 

Apart from the above-described applications, you can also use neodymium magnets at your home for creative purposes. These are not limited but may include cutlery bolder, decorations, metal detector, homemade compasses, jewelry clasps, picking up nails and screws etc. However, there are some important precautions you must take to ensure a safe use of these strong magnets. Due to their extremely high magnetic force, you need to be extra careful while handling them. Make sure you have no ferrous object with or around you. Otherwise, those ferrous objects will fly towards magnet causing serious injury. Also, keep neodymium magnets away from children. Even you should not give magnetic toys to children freely. This is because if these magnets are swallowed, they can cause digestive and respiratory problems leading to death. Finally, keep in mind that very high temperatures can decrease the magnetic strength of neodymium magnets.

Worth of Magnet in Modern Technology

There is no doubt about the usefulness of Neodymium magnets, but still there are some hazards associated with the use of the product. Neodymium magnets are strong enough. So handling of this magnet needs some extra care and diligence. It is advisable to protect your hands with gloves and eyes cover with goggles while handling Neodymium magnets. People having exposed to the magnetic field of Neodymium may have other health hazards as well. Sometimes it happens that when you are dealing with big magnets your finger get crushed due to the magnetic field and sometimes due to the attraction it can break your bone and tear the skin also. Magnets should be kept away from the reach of small children. It can take their life if in any way they are swallowed.

Neodymium magnets are mostly demanded for its strength and magnetic force. That is the reason why it can be used in most of the industrial and commercial application. The strong neodymium magnet is permanent in nature and it is almost impossible to demagnetize the material. Due to its outstanding strength it is able to be used in the production of small parts. So many magnetic application used in household practices is possible through the use of this neodymium magnet. applications where Smaller magnets are needed like ear buds for music, toys, motors and other appliances can be made out of a neo magnet, because its rare-earth element possesses a greater magnetic field.

The modern technology needs the assistance of the magnetic field. The technology of mechanism of Computer monitors, CRT, CD, DVD and TV screens helps in generating images making use of magnets. It also contributes to the medical science in generating images through Magnetic resonance imaging (MRI) machines. It enables the doctors to view of what's happening inside the human body through the use of both magnets as well as the principles of magnetism. We all use ATM machine and different type of debit and credit cards. All this application use the magnetic technology to store important user account information and details in a magnetic strip for easy and fast retrieval of the of information. You may hear about a magnetic can opener. It is a device that holds the lid of the can with a strong magnet inside it. The device than cut the edge of the lid and enable you to take the can from it. There is a quick tug on the lid which pulls it off and you can get the can without the lid.
