Magnetism without Iron Discovered

There is a new kind of magnetism from a mineral known as herbertsmithite, which has been developed by a group of researchers. The researchers conducted the first measurements by laser pulses of low frequency to show the details of this mode of magnetism.

The elements of magnetism are never stable in this mineral thus a rare kind of fluid magnetism which is referred to as “quantum spin liquid.” This is actually the opposite of conventional magnetism which is present in Ferro magnets.

In conventional magnetism the forces are in the same direction therefore giving each other back-up. They could also align themselves in directions that are opposite thus cancelling the whole magnetic field of the material.

There have been previous observations of spin liquid state observed in the herbertsmithite but a detailed analysis of the material’s electrons response to light has never been given. This analysis is what holds the key in deciding which of the many theories about the material are right.

The teams from Harvard University, Boston College and MIT have all conducted successful measurements. Their analysis is in a paper in Physical Review Letters. The co-authors are the Biedenharn – MIT’s Associate Professor of Physics, Chun Hung Lui, graduate student Daniel Pilon, Nuh Gedik and other four persons.

Laser pulses whose duration was a trillionth of a second were used in conducting the measurements. What was revealed is that the movement of electrons was controlled by the magnetism. The observation above is then seen to support some theories which had not been proven experimentally.

“We think this is good evidence,” Gedik says, “and it can help to settle what has been a pretty big debate in spin-liquid research.”

Gedik’s counterpart, Pilon also explained that there are several theories trying to explain the formation of spin liquid state in herbertsmithite. He also added that there had never been any experiments to differentiate between the theories thus the belief that their experiment is the first evidence to do so.

The quantum spin liquids was a concept first heard in 1973 but it is until now that the measurements clarify everything. According to Gedik, potential applications at this initial stage are still difficult to predict.

A professor of physics at the University of California at Santa Barbara, Leon Balents who was not involved in the research said that the observations made during the measurements are very crucial when it comes to understanding the nature of spin liquid state.

The research team was supported by MIT’s Tian-Heng Han and Young Lee, Willie J. Padilla (Boston College), David Shrekenhamer and the U.S. Department of Energy.

Data Storage Meets Magnetism

Soon and very soon we could be having fast and dense energy saving chips for computation and memory purposes.

The results of this phenomenon are that it will reduce the amount of energy used to store or get a single bit of data by a factor of ten thousand. These findings are published in a journal known as Natures Materials.

According to the Journal’s senior author, Geoffrey Beach, there are many hints that have been reported for years now concerning the phenomenon. The only thing is that these reports lacked proper explanation till now.

Beach also added that the new findings could take away all the limitations associated with the use and control of magnetic materials. To him, this was a whole new way of approaching the design of materials that are magnetic.

The very center of the phenomenon is not within materials that are magnetic but rather in what neighbors them. What the research team did is using films of ferromagnetic material that are very thin and deposited them on a metal base which had an oxide layer material at the top. How the ferromagnetic layer behaves is actually dependent on the metal that the oxide layer is on.

Materials that are ferromagnetic have two poles, one for north and the other south. When they are used for storing data on a hard disk the result is separation of domains that are tiny on the surface. This makes the poles point up or down and this represents zeros.

The domains usually move along the surface following the same direction as that of the electron flow.

In previous cases the result was movement in the other direction and this left the researchers disturbed. It is the MIT team that discovered that using a slab of platinum is what brought about the backward movement.

In situations that were similar the direction was normal unless the film was put on a metal tantalum. This showed that the Ferro magnet itself was not responsible but what it was next to was. Tantalum and platinum are not magnetic thus they do not have any effect on magnetic material.

In both cases there is an effect that changes how the magnetic domains switch one another that is from up to down and vice versa. This change is random but in the sandwich of thin film there is an alignment in the rotations and there is consistency in turning.

It is this strange effect that has enabled researchers to show that domains are powerfully pushed by currents than by materials that are conventional. They also showed that the direction of a domain can be controlled through the selection of the underneath metal that is non-magnetic.

“There are very few systems in nature that have this preferred way to rotate,” Beach says. Examples are those molecules that constitute the basis for life, including those assembling in the DNA molecules.

Additionally, a few magnetic materials have shown this property, “but only in very exotic structures,” he says: at temperatures just slightly above absolute zero, and only in a perfect single crystal.

Fridge Magnets that Top Up Your Shopping List

Worldline, a transaction services provider, has come up with an electronic fridge magnet dubbed ‘Connected Kitchen’. This magnet targets online food retailers and allows consumers to add everyday items to their shopping lists even as they continue using them in their homes.

The device works by scanning the product barcode or the consumer can use the speech recognition feature to voice out what they would like to add. R&D engineer Herault Colombe said, “It is a connected device, able to connect to our cloud services to help customers make their shopping list. In order to do so, the customer can use the embedded 2D barcode reader or record their voice”.

The magnet does not require an application so as to facilitate the interaction. There are buttons on it to activate the voice recognition and the barcode reader. It remains stuck on the fridge like a normal fridge magnet. But whenever the consumer remembers something they will need they can either use a sample of what is already in their home to give the barcode.

They can also speak the items they would like to buy into the devices. The voice recognition would more often be used for items without barcodes like vegetables and the like.

Once the buttons are pushed on the device the information is sent to the R&D cloud service and added to the shopping list. You can check through the information on Worldline’s mobile app or website later if required.

The communication between the device and the cloud services is completed using Wi-Fi which originates from the consumer’s home router. Research about the right products based on the barcode and the recognition of the text from the spoken words is done by the cloud services. Connecting to the retailer’s cloud service is also done using the R&D cloud services and all these form the bulk of the operation.

This device is bound to make shopping easier and more convenient for the consumer since it eliminates the written shopping list posted on the fridge door. It will also reduce the amount of time a customer will spend finding a piece of paper so as to write a list before they forget the items they were to write down.

It makes the whole process an instant affair and confirmations can still be made on the website and app so a change of mind can be effected as well. It will definitely revolutionize shopping for the consumer.

5 Interesting Uses of Magnets

Magnets usually conjure up the image of complex applications in different industries and in the home they are used to hold items on the fridge door, top on the list being next week’s shopping list, your toddler’s drawing from school and a duty roster for your older kids.

More uses have been devised for the simplest of activities in the home without having to break the bank. Magnets can now become part of your daily or weekly routine if you use them in any of the following ways.

1. The remote control remains faithful until the batteries die and need changing. Removing the batteries is always a task and a half for most people as the batteries sit tightly inside the remote. You can use a magnet to pull the batteries out instead of struggling with them for hours on end.

2. Pens have the uncanny habit of disappearing whenever they are required and keeping them in place is not always possible. Making use of the magnet to keep a pen glued to a surface means you will always know where to find a pen when you need it. A magnetic pen can have a magnet between the body and the handle so that it can be stuck to any surface where it will stay put.

3. Items drop down drains and reaching down for them is not always a pleasant experience. A magnet tied to a piece of string can be lowered into the drain to attract the item to it and then pulled out. It takes much less time and is a lot cleaner.

4. When a wall is painted, screw and nail heads may get covered. Looking for these may be a difficult task which can sometimes lead to chipping the freshly-done paint. Running a magnet over the wall may be an easier way of identifying the nails and screws and once you find them you can leave the magnets in place as markers.

5. Snacks like chips get soggy if not finished when they are opened. Magnets can keep them fresher for longer in a simple way. Once the bag of chips is opened but the contents not cleared, the bag can be folded over as usual and two magnets placed on either side of the bag. This keeps them fresh and crispy for the next time you will open the bag.

Magnets don’t have to be the serious gadgets only but can be used to solve simple problems in the home as well.

The Developing Role of Permanent Magnets in Renewable Energy

The developing role of Permanent Magnets in renewable energy production along with the environmental protection is a very worthy topic. An upright permanent magnet should produce a high magnetic field with a near to the ground mass, and should be constant against the inspirations which would demagnetize it. The desirable properties of such magnets are usually indicated in expressions of the remanence and coercivity of the magnet materials.

In 2005, the rate of total universal energy usage was about 15.1 TW. As a point of reference, Canada and the USA consume about 25 per cent of that energy.  A number of organizations project that energy consumption will grow by over 50 per cent in the period from 2005 to 2030, and obviously, that energy has to come from anyplace. In all of these technologies, permanent magnets have a part to play, though in some cases it might not be as noticeable as in others. The habit of permanent magnet technologies in the oil and gas exploration and production industries has seen a dramatic reduction in the effect of these undertakings on the environment.

The key way that permanent magnets are generated is by heating a ferromagnetic material to an important high temperature. Permanent magnets are vital for their industrial uses particularly when it comes to power generation and electric motors. In turbines and generators permanent magnets are essential to turn mechanical motion into energy. They are also noteworthy for electric motors in several electronics using the reverse of the induction of electric current to make mechanical energy.

A permanent magnet is a magnet that doesn’t lose its magnetic field. Because of the bearings of its domains, a permanent magnet is a magnet. Domains are the minor magnetic field inherent in the crystalline structure of ferromagnetic materials. A magnet is shaped when certain circumstances cause separate domains in a ferromagnetic item to be all channeled in the same direction. However the manner used in most cases weak magnets can only be made. This is typically by direct contact with an obviously magnetic material or by continuously putting an electric current through it.

Using magnets to cater energy requirements

It is safe to say that it is conceivable to utilize magnets for vitality?

Yes, not just is it conceivable it has been utilized for a considerable length of time. In the late 1800s they were utilizing this strategy for force.

It has created a ton since that time and gets to be exceptionally questionable yet yes utilizing magnets for vitality is completely conceivable. In the event that you read on the historical backdrop of power you will find that Benjamin Franklin and Thomas Edison are not by any means the only two included in making power.

A standout amongst the most paramount things about utilizing magnets for vitality is to know where to place them because of the force they have. When you focus the draw and the power that it has you will understand that this is a great wellspring of force.

As a result of this idea that was begun in the late 1800s we have a ton of developments. There is an approach to utilize magnets on an engine to permit that engine to run consistently. This is not new innovation yet has not been made well known on the grounds that it cannot be charged month to month. In the event that you make your power you won't be charged by the force organization. Numerous feel this is the reason this innovation has not been imparted.

Since this doesn't depend on the wind or sun it is the ideal technique to execute. Utilizing magnets for vitality implies you can manufacture an engine one time and it will run for a considerable length of time without any more financing. This engine will then control your house without an expense to you.

Utilizing this engineering is not as new as you accept it simply has not been made open.

Is it possible to use magnetic earth magnets outdoors?

Lanthanide components are ferromagnetic metals. This implies that they the ability to be charged much the same as iron. Be that as it may, their curie temperatures (the temperature at which they lose their attraction) are normally underneath the typical room temperature. This illustrates why rare magnets are not suitable for outside utilization. In most cases, open air temperatures are normally higher than room temperatures. This prompts demagnetization of the magnet and consequent waste. Hence, utilization of uncommon earth magnets in outside environment is not fitting.

Rare magnets are made up of a combination of neodymium, iron and boron (Nd2fe14b). They are the most vigorous and practical kind of rare earth magnets. These magnets have comparable properties to Samarium Cobalt uncommon earth material with the exception of, that they are effectively oxidized. This implies that Nd2fe14b magnets have a penchant of consumption. The Fe some piece of their name speaks to iron and iron is a standout amongst the most consumption inclined metals. Nonetheless, this issue is not difficult to manage. Various defensive surface medication methods, for example, nickel, zinc, gold and tin plating give the essential consumption assurance as and when needed. Epoxy pitch covering is an alternate defensive surface medicine technique that is additionally very basic.

These surface medicine methods guarantee that the attractive material does not experience dampness. On the other hand, if the covering endures any type of harm, dampness or water may experience the attractive material underneath and reason rusting. Ndfeb magnets have one of the most elevated vitality items (very nearly 52mgoe). Subsequently, they are mechanically stronger than Samarium based magnets. Their high-vitality item makes them suitable for inventive provisions that oblige a reduced plan and low assembling expenses.

Other advantageous aspects of these magnets could be their unnecessary coercive power (demagnetizing compel that is measured in Oersteds and is discriminating in lessening a magnet's flux for every unit zone or prompting) and normal temperature security. Much the same as any possible material that exists on earth, Ndfeb magnets have their disadvantages. This incorporates low imperviousness to erosion when inadequately plated or covered and low mechanical quality. Rare magnets are connected with gigantic alluring strengths. This characteristic accompanies its rare risks. Rare earth magnets that have widths of recently a couple of centimeters have the capability of bringing about genuine real damages. This is particularly thus, if a body part gets trapped amidst the two magnets. In a few cases, these magnets have even brought about broken bones. That is the way effective uncommon earth magnets could be.

How China is planning to dominate the rare earth magnet industry

Rare earth may focus the fate of clean vitality.

I'm not discussing Gil Bridges and Ray Monette of the rock band Rare Earth, noted for such hits as "Get Ready" and "I Just Want to Celebrate," despite the fact that that does bode well. The band is back together and touring, truth be told.

This is about potential Canworld command by China of an industry so vital, its prosperity or disappointment may mean the distinction between survival and mass clearing in low-lying nations like Bangladesh.

A significant part of the clean vitality industry relies on to a great degree dark components that now be known as rare earth. They have names like lanthanum, cerium, yttrium and neodymium and are utilized within the production of electric auto batteries, wind turbines and sun powered boards. China has used the past a few years bolting up supply of these components, arranging ahead and betting on their quality heightening.

Also the stakes are high. The late study, "Vitality Policy," by Stanford University educators Mark Delucchi and Mark Jacobson says wind, water and sun based could supply the greater part of our vitality needs in 20 to 40 years. While that may be impossible given today's vitality blend, the segment is certain to expand notwithstanding the mastery of progressively immoderate and harming fossil fills.

Rare earth components, while generally plentiful in the Earth's outside layer, are elusive in "minable focuses," as the U.s. Land Survey clarifies in its 2010 rare earth report. Along these lines the issue - and the name.

China, as per USGS, has stores of 55 million metric tons, while the United States has 19 million metric tons. Both nations command known stores. Nonetheless, China is better situated to exploit its mines.

"China represents 97 percent of the overall rare earth metal preparation and the nation's new fare standards have brought about costs to skyrocket," compose Euan Sadden and Kerry-Ann Adamson of Boulder, Colo.-based Pike Research in the May 2011 report "Rare Earth Metals in the Cleantech Industry."

That means if an organization needs to fabricate batteries, wind turbines or sun oriented boards, it likely must get its materials from China. Notwithstanding, the Chinese are barely slumps at exchange and their makers have recently started to overwhelm generation of sun oriented boards. Examiners say they plan to the same with whatever is left of the cleantech business.

U.s. also European organizations looking to construct the monstrous authority locales for wind may end up with no other intense elective other than buying from Chinese suppliers. Also for a developing industry subordinate after falling costs for more general selection dependence on a solitary source could be awful. 

Ian Fletcher, creator of "Unhindered commerce Doesn't Work" and Huffington Post blogger, outlines the verbal confrontation in basic terms.

"Why are they significant? Case in point, the purported rare earths around these materials are required to make the super-solid magnets that are required at whatever point you need to mechanically produce (or expend) power productively," Fletcher composes in a late post. Also he says that as per gauges in the late book "Red Alert," by Stephen Leeb, a 3-megawatt wind turbine holds something like 2 tons of rare earth metals.
