Magnets Safety

Magnets are the products used for different application. Not only it is incredibly helpful for practical purposes but can be used for fun as well. However magnets are having some hazard that we almost ignore. So it is very important to know all about it in detail before having a magnet. If you are ordering magnet online then it is significant for you to check the product label clearly. Sometimes you will find a warning brochure included with the product. The following are some important tips that should be kept in mind while handling magnet.

Magnet has its magnetic field. If you place two magnets side by side, you can see how they attract each other. Even small magnets have a great magnetic power.

Many types of magnets are available in the market. Among them the commonly used magnet is neodymium; it is used in many applications. Neodymium magnets are the strongest type of magnets in the earth. The magnetic force that they use is too high. Sometimes the force at which it attracts the other magnet may cause harm to others in case necessary measures will not be followed. You should be cautious enough and should take safety precautions while dealing with magnet else it can cause you serious injury.

 The following are some safety precautions that should be considered always while handling magnet.
  • Keep your eyes away from the magnet. Try to wear a wear safety goggles while you are handing large magnets.
  • For the safety of your hands do not forget to wear gloves when you are dealing magnets to prevent pinching.
  • Do not allow your children play with Neodymium magnets. It may cause harm to them.
  • Always keep magnets at a distance of at least 20cm away from sensitive storage and electronic devices.
Neodymium magnets may cause hazard to the health of your children. So they should never be allowed to play with the same.  It has been seen that small magnets sometimes cause blood blisters and cuts while tiny magnets can be the reason on severe injury if swallowed.

It is observed that if more than one magnet is swallowed, then there is a chance that they can attract each other all the way through the walls of the intestines. There is a chance that they get stuck and pinch the digestive tract resulting in major swelling. Often it can be serious enough requiring surgery and even life-threatening injuries. So it is advisable to keep all your neodymium products out of the reach of your children.

Types of Ferrite Magnet

The good thing that a Ferrite Magnets  has is the easy availability. As the raw material it uses is available in sufficient quantity, there is no chance of having a scarcity in the production Ferrite Magnets .It is a type of ceramic magnets. And like all other ceramic magnets, it has the easily breaking quality. But due to its high-coercive attribute, demagnetization is not possible. The raw material used to make Ferrite magnets is the ferric oxide. It is a cheap magnet among all other magnets available in market due to its easy availability. Moreover, it is a magnet that can be used in flat forms. For the preparation of Ferrite Magnets, the magnet is mold by pressing with ferric oxide dust. Then it is to be heated in a furnace in a temperature of 1200 degrees Celsius approximately. Therefore they are fitted for mass production and can be available at economical prices. The two basic types of Ferrite magnets are Anisotropic Ferrite and Isotropic Ferrite.

Anisotropic Ferrite Magnet

As we know the coercive force in this magnet is strong, it cannot be demagnetization. It is a ceramic magnet. Ferrite magnet is extremely anticorrosive. The unique feature of this magnet is that, it is best fitted for a flat shape magnet to use. While the weak point here is that it is supposed to be easily broken. From long back Ferrite magnet is used in the mechanism of audio speakers and headphones. But now due technical innovation it gets lighter. In recent days Ferrite magnet is used progressively more for automobile motors or generators.

The other saving grace is the abundant supply of raw material of Ferrite magnet. As there is plenty of ferric oxide, used as raw materials of Ferrite magnet, it is possible for the manufacturers to produce the magnet at the lowest price amongst all other present day magnets.

A wet type of Granulated powder of ferric oxide mixed with a little portion of strontium with also water into a slurry state. After that it has been poured and pressed in a metal mold. Then the real molding process starts. It is done in a compact magnetic field so that even smallest units of the magnet are aligned in a certain specific direction, building them an Anisotropic Ferrite magnet. Following undergone through the heated furnace, thus the magnets are refined and polished into the preferred sizes of requirement and rinse for a finishing touch. 

A dry type Granulated powder of ferric oxide is pressed in a mold, and then heated in a furnace to make this magnet. However, the magnetic force present in it is approximately 7% weaker than the wet type of magnet.

Isotropic Ferrite Magnet:

We can get Isotropic Ferrite Magnet by mixing a correct portion of ferric oxide with a few percent of Barium. It is powered with granulated before being pressed. Her no need to do the molding with a magnetic field. The magnetism present in it is about half of that of an Anisotropic Ferrite magnet as the direction of the magnetic force aligns is in an axial or radial direction.

Things You Must Know About Ferrite Magnets

Ferrite Magnets are the Sintered magnets also known as ceramic magnets made from the material like ferric oxide, which you can find abundant in supply. Therefore you can expect a consistent flow of Ferrite magnets throughout the time. It can be available in lower and budgeted prices in a continuous manner. Among all other magnets in the market it is supposed to have the lowest cost possible. Because of its high-coercive feature, it will have a less chance of demagnetization. This type of magnet is best suited to be used on flat forms. This type of magnets can be produced by pressing a fine-powder of ferric oxide. Then mold and heated keeping it in a heat of approximately 1200 degrees Celsius. The main benefit of Ferrite Magnets is that they are resistant to corrosion. So they are best fitted for mass production and can be available in a lower rate. There are two mare categories of ferrite magnets. Those are: Anisotropic Ferrite and Isotropic Ferrite

Some distinctiveness attributes of Ferrite Magnets:
  • A consistent accessibility of raw material makes it available all the time.
  • It can be ensured at a cheap price.
  • Enhanced coerciveness quality makes it less likely to demagnetize.
  • It is however identical to other ceramics ferrite magnets as it is brittle, and at the same time is fit for mass production as it is made by molding with a fine powder coating of ferric oxide.
  • Though having a sable gravity of 4.8g/cm3, as compared to other magnets these are of much lighter weight than any other magnetic products.
  • You can place it 2-10 poles on a flat surface.
  • It has an additional possibility to magnetize multi-poles along the circumference of the magnet that is the reason why it has a wide range of application in meters and motors.
  • Useful for the materials to create rubber magnets and plastic magnets.
Ferrite magnets have a wide range of application for its distinguished features. It is a strong material substance which can be used in various products, like device for electrical instruments, stationery products, automobile motors and generators, household appliances, and healthcare equipments as well. Now it is used in industrial purposes to run extreme machineries. Ferrite magnet is extremely anticorrosive. But the main drawback associated with it is that it is fragile in nature, means cannot withstand against more pressure.

Magnets in Generators

An electric generator is a device which turns the mechanical energy into electrical. A generator is a machine that forces electric current to flow through an external circuit. The mechanical energy come from turbine steam engine, internal combustion engine, water falling through a turbine steam engine, wind turbine. A generator is helpful in providing almost all of the power necessary for electric power grid.

An electrical motor do the task of reserve conversion of electrical energy into mechanical energy. Therefore the mechanism of motors and generators are almost similar. Major motors are used to generate electricity mechanically and for that Ferrite Magnets are very useful.

Two types of generators are there. The first one is Alternative current generator while the second is Direct current generator. Horseshoe-type of magnets is useful for both sorts of generators. The use of this type of magnet is useful in case of anticlockwise rotation of the shaft. Thus it is advisable to use this type of magnet when the shaft is rotating in an adverse direction. At that time the force is going upwards while the magnetic field lines are moving left to right. As a result Ferrite Magnets enables the current to flow in a circuit continuously to create electricity.

There is a link between electricity and magnetism. You can say that a generator is merely a device that is responsible to moves a magnet near a wire to make a consistent flow of electrons. The function that forces this movement varies to a great extent, starting from the steam engines to the nuclear fission, however the basic principle remains equal for all.

You can compare the function of a generator with a water pump try to push water through a pipe. The difference is that instead of water the generator uses Ferrite Magnets to push electrons along. The principle and mechanism is same. In case of a generator the magnet forces a certain number of electrons along and at the same time apply some amount of strength and pressure to the electrons.

The number of electrons used in an electrical circuit is the electron in motion is known as current or amperage. This is measured in amps. Voltage is the pressure used for pushing the electrons to function. It is measured in amps. The capacity of producing voltage of a generator is 1 amp at 6 volts at a spinning of 1,000 rotations per minute. The voltage is however the amount of pressure behind those electrons.

Many people make use of magnets for the task of sticking invitations, some important reminders, old memorable photographs and other important notifications to your refrigerator. It is true that magnets of high quality are very useful for many house hold purposes. So, while renovating and designing your house keep this in mind and do the job accordingly. Magnets can help you solving frustrating problems of your home. So always consider to use magnets in different ways to fix the household issues.

Following are some useful techniques of using magnets to improve your lifestyle.

Firstly it is useful for cleaning up purposes. If you spilled some nails, pin or staples over the floor. You don’t need to collect them with stabbing your fingers. Just float a magnet over the surface. You can easily pick the fallen objects up.

Using magnets you will be easily store and hold various essential household items. You can fix a magnet in your fridge door, or to the bathroom door to store small things on that. Even you can put a magnet on the top of an ironing board so that after folding it also it will stay in proper place.

You can attach a block magnet to the cabinet and drawer of your bedroom to keep it closed always. It can be attached to the inside panel of the drawer at one side with the help of a double-sided tape and attach the other one to the door or drawer itself. The main thing is that both the magnets are lined up correctly. So that when you close the drawer it will keep the draw shut.

Sometimes we find our batteries get stubborn with its case and its very irritating trying to get a stuck battery out of its case. But the thing will be easier for you if you do it using strong magnetic power. So what you need to do is to put a magnet over the battery and see how easily it will pop out.

If you want to display your knives, then instead of buying an expensive knife holder, you can trust on a bar magnet. It will improve your home décor as well as is safe in use. The fashion of display on the wall will be appealing to the eyes.

You can also make an invisible tool holder through inserting a disc magnet into it. Then it can be very well used by drilling a series of holes in the back of a wooden board. You can fix it over the wall and can hang all your favorite tools onto it.

The Journey of Magnet

Since thousands of years, Magnet has been in use for mankind. The Chinese literary work in 4th century B.C.E. is the first evidence to magnetism dates. In a book named “lodestone attracts iron to it” it is clearly defined that Lodestone is a sort of magnetite metal along with fine unique crystalline structure that can predictably create an effect of magnetic field and in this manner attracting and magnetizing iron. Through the end of 12th century A.D., some Chinese sailors were taking help of magnets as compasses to identify the directions for sea navigation.
History tells that at some point of time it was believed that lodestone has the quality to keep skin look glowing and youthful. That is the reason why, Cleopatra, for many years was slept on a lodestone. Not only the Chinese but the beneficial repute of lodestone was passed on to the Greeks, very soon, and then they also start using magnets for healing.
It has been seen that at first the Chinese discovered the medicinal effect of Magnets and later rest of the people follow the same. Still today Magnets are known for the first line treatment for numerous common health complaints. A treatment of warm lodestones placed strategically on the back of a back-ached patient is an effective measure to avoid back pain. In the modern days also the medical science is not far away from the use of magnetism. However you will be surprised to know that magneto encephalography (MEG) is used to gauge brain activity. Using shock therapy is another example of the application of magnet in medical science to start a stopped heart.
Today, we all are aware of the use of magnets in the field of industrial and mechanical applications. Now magnetic power is very commonly used to drive all electric motors and electric generators. All the electric motors are dependent on magnets for their proper function with electrical coils. So, while the current move, magnet also follows the same sequence. Electro-magnets are used in the common machines like telephones, telegraphs, computers, door bells, cell phones and  tape recorders, as well. Apart from this Electromagnets are also used on cranes to deal with the heavy loads. Construction sites can be cleaned up by truck mounted magnets to prevent nails in vehicle tires whereas the industrial conveyor systems help to pull metal parts out of various materials. The constructions sites can be easily cleaned with truck mounted.
As the age advances magnet technology is becoming progressively more important. Thus it is believed that as the time passes on the technology continues to build up, and our perceptive of magnets will surely develop and go on playing a significant role in our daily lives.

The Magnetic Sense That Could Save Sharks

It is not your bleeding but your breathing that enables a shark to locate you in water. As your heart beats it releases electric impulses that flow with a magnetic field.

It is the same information that has been used by scientists from the University of Stellenbosch to develop shark barriers. These barriers will protect swimmers from the sharks and sharks from frightened swimmers. The barriers will also protect other sea creatures from shark nets.

Why protect a predator?  “Sharks play a critical role within the marine ecosystem,” said Craig O’Connell, who’s a PhD candidate and research fellow at the University of Massachusetts Dartmouth and Stellenbosch University respectively.

There are beach nets and yes they do provide maximum safety for the swimmer but the opposite goes for the shark population.

The main threat to sharks everywhere is fishing and this has even led to the great white shark being declared a vulnerable species.

Sharksafe is a magnetic barrier being worked on by O’Connell and his team of researchers. This barrier will keep sharks away from beaches and also protect other marine creatures.

The team bases its technology on the sixth sense of sharks and that is the ability to perceive magnetic fields. This brings about the question if sharks make use of sensory organs?

The sensory organs used by sharks are known as ampullae of Lorenzini and they are located in their heads. This is what enables them to note electromagnetic radiation. It is even reported that sharks have the greatest sensitivity than any other animal when it comes to electricity.

The SharkSafe barrier involves placing magnets in Perspex tubes, which are disguised as a kelp forest. “The point is to mimic a kelp forest so that it [appeals] to the shark’s visual system and magnetic electro-sensory system,” O’Connell said.

They have been doing this work on a larger scale at Dyer Island and so far have been successful as they report that more than sixty sharks never crossed the barrier though they interacted with it.

The project gets logistic support from Professor Conrad Matthee - Stellenbosch University’s principal Investigator of the university’s evolutionary genomics group.

Professor Conrad said that the next stage will be an exclusion barrier whereby sharks can never come in. He and his partners are testing this on the white shark. They have tested the same on Zambezi and tiger sharks.

The sharks do get a little discomfort which O’Connell described as normal. Their efforts are driving at keeping people and sharks apart without getting the animal hurt in the process.
