Magnetic Jewelry Clasp

The name Neodymium originates from the Greek words 'neos' meaning new and 'didymos' meaning twin. It was discovered by Baron Carl Auer von Welsbach in Vienna, Austria in 1885; however it took another 40 years to isolate it in its relatively pure form in 1925. He separated neodymium, as well as the element praseodymium, from a material known as didymium by means of fractional crystallization. Sounds complicated? It is, so I won't go into it here, but suffice to say as scientific understanding evolved so the purity of the finished product improved and can now be produced to a purity of

One of the most appealing characteristics of neodymium magnets is their relatively low cost however, the bulk of current production is from China, and concerns have been raised recently in consuming countries because the Chinese government has recently imposed 'strategic materials controls' on the element. That's enough politics!

It is an incredibly useful element and is a key component of an alloy used in the production of lightweight magnets for electric motors of hybrid cars, in generators for wind turbines, loudspeakers as well as being a popular additive in glass, giving it a characteristic reddish-purple colour, especially useful in lasers emitting infrared light. You might also find these small but powerful magnets in your cell phone or your computer's hard drive and is also one of a number of metals in an alloy commonly used in cigarette lighter flints. There is also much information out there regarding its benefits or otherwise, in pain relief of conditions such as arthritis, back/spine pain, fibromyalgia, carpal tunnel syndrome, sinus and stress headaches, asthma, muscle spasms, toothaches, strains and swelling, joint pain and fractures. So you can see that somewhere along the way you have probably owned or used a piece of this 'rare earth element', (though it's actually not rare at all, in fact its abundance in the Earth's crust is about 38mg/kg and Neodymium reserves are estimated at 8 million tonnes!).

Neodymium magnets are made from a combination of Neodymium, Iron and Boron and are extremely powerful, this increased strength has inspired some new applications such as magnetic jewellery clasps and magnetic building sets for children and herein lies the fun aspect.

One such inspiration is the Wiki M-Cube it's a puzzle like you have never seen before! It consists of 216 highly magnetic Neodymium rare earth magnets with a durable nickel plated surface, far more powerful than your average fridge magnets. Each one has a north and south polarity, allowing you to make a myriad of different shapes and patterns in both 2D and 3D. There is no one solution, but it is a puzzle if you choose to set yourself challenging targets. Even returning the cube to its original shape once dismantled is harder than it sounds. It can be shaped into funky jewellery or sculpted into inspiring shapes and when you get bored with your creation you just have to start again. It will entertain you for hours and can help to relieve stress, develop the creative side of your brain and relieve boredom. It makes the perfect executive toy and would look stylish on any office desk. Your kids will also love it and you'll be prising it out of their nimble fingers at every opportunity (though not for children under 36 months due to small parts). However, take heed, once you start, you cannot put it down, it's seriously addictive!

So, neodymium for science or for fun? Try the Wiki M-Cube then decide! I think your kids will agree that physics just got that little bit more interesting.

One version of 'obvious applications' is the fixation of something to something else. Aside from providing nearly endless amusement applications, this is a great thing for organization. These magnets have the advantage of being incredibly strong and able to attach through almost any material. They can hold a stuffed toy to the dashboard of your car, and they can just as easily hold a kitchen appliance to the underside of a cabinet.

If there is no need to attach kitchen appliances to cabinets, neodymium rare earth magnets would be great in the garage. Organize tools, hardware, even things like a bicycle. When all that is needed is two magnets and some glue, it really could not be easier to set everything up just right.

Along with the household applications, magnets have long been used in healing. It is believed by some that pain is caused by an imbalance of the body's natural electromagnetic field. To this end, some licensed practitioners use magnets to restore balance and lessen, or even entirely get rid of, pain. During a magnetic therapy session, the customer lies on a massage table or something similar while the practitioner places magnets of varying sizes and strengths on pressure points. The magnets can be moved slowly over the body also, depending upon the wishes of the one needing healing. In order to promote peace and comfort, there can be music and light massage along with the magnet therapy.

Though these magnets can be a great asset to anything from commercial applications to alternative medicine, there are dangers associated with them. Due to their extraordinary strength, even the smallest magnet can be dangerous to people. If a child or even an adult swallowed two, it could result in a pinched bowel, which is horribly painful at the least and fatal at the most. Larger pieces are strong enough to break bone if an unfortunate person were to be standing between the magnet and the metal it was attracted to. All sizes can cause injury due to shrapnel caused when two of them meet at high velocity. The magnets are made from delicate materials, so if they slam into each other it can create shards that can be harmful.

Neodymium rare earth magnets are an invaluable asset to the industrial community with their applications in things like power tools and computer hard drives. They are also immensely useful to the average Joe as organizational tools and alternative therapy aids. Despite the dangers, they can be a wonderful thing to have around the house.

Rare earth neodymium magnets are also used in the health industry. Magnet therapy is becoming more commonplace and can help to relieve pain. These magnets are also used in therapy sessions for those who are suffering depression. Neodymium magnets have many healing properties and are commonly called healing magnets.

Neodymium magnets, like most other rare earth magnets, are very vulnerable to corrosion. These magnets are usually given a nickel or copper plating for protection. However, the coating does not make a neodymium magnet any less powerful. While these magnets are easy breakable and can be cut into any number of shapes, they are nearly impossible to demagnetize.

A person who buys Neodymium rare earth magnets should be aware of the dangers that they pose. Neodymium magnets should never be left in the reach of children. These magnets will smash through any substance if they are left too close to each other. People have even had bones broken as a result of mishandling these powerful rare earth magnets. Neodymium magnets will also wipe the data of a disc or credit card if left too close to either of these items. A person who buys these magnets should exercise extreme caution and store them properly at all times. Any neodymium magnet that is larger than a few centimeters is powerful enough to cause damage.

Neodymium magnets can be easily purchased online. These magnets come in well over half a dozen shapes and are usually sold with nickel or copper coating. There are arc, rod, cylinder, block, cube, disk, ring, sphere, triangular and star shaped neodymium magnets. These magnets can even be custom made to suit a buyer's needs.

Neodymium magnets are fascinating. Contrary to what the name implies, they are not all that rare. They are found in everyday appliances; without these magnets many modern inventions would either cease to exist or not function as well as they presently do. These magnets can easily be purchased online. Prices vary depending on the size and shape of magnet needed; however, these magnets are becoming cheaper all the time. Neodymium rare earth magnets can be used for many purposes but should always be used wisely. One should take these magnets seriously as they are very powerful and the misuse of neodymium magnets can cause serious injury and even death in some cases.

What Is A Neodymium Magnet?

Neodymium is known as a rare earth element. This name is something of a misnomer, however, as neodymium is actually quite plentiful in the Earth?s crust. It is quite difficult to mine, though, since it is not often found in large quantities, instead being spread out relatively evenly in the ground. There are three main properties that set neodymium magnets apart. The property known as ?remanence" is a measure of the magnetic field strength. ?Coercivity" is a measure of its resistance to demagnetism. Finally, its ?energy product" is a measure of the density of its magnetic energy. These three properties are far higher in neodymium magnets than in almost any other kind.

Uses and Applications

In any situation where small size and great magnetic strength are valued, you will likely see neodymium disc magnets. You can find them in many cordless power tools, for example. A typical DIY drill may well be driven by neodymium magnets, and they can also be found in many other motor applications. Hard disk drives in computers also often use this material, since the small size of a laptop is exactly the sort of place in which its unusual properties are best used.

Dangers

The extremely high magnetism can cause indirect dangers. Magnetism is not itself a dangerous force, but a strong attraction between two metal objects certainly can be. One such example is that of children?s toys. There have been reports of young children swallowing tiny neodymium magnets. A single magnet is rarely a problem, but if there are two or more of them then serious problems can occur. The two magnets can attract each other inside the gut and they become stuck. This usually requires surgical intervention.

Conclusion

Neodymium disc magnets are a fascinating invention. The material is exotic and difficult to procure, and it has extraordinary properties when used as a magnetic material. You can find it used in many everyday applications such as computers and drill motors. Even some children?s toys use these magnets, but beware of the consequences of playing with extremely strong magnets; they can be fatal.
