Neodymium magnets for sale
We all use a neodymium magnet in a single form or the other; we only don't know that we do. There are plenty of uses and advantages of this amazing piece of human invention ones we are unaware of. One can possibly easily find a neodymium magnet in the hard disk of a computer, headphones, and loud speakers for example. And these magnets are immensely powerful and give us to do things where normal iron or ferrite magnets prove ineffective.

So what are neodymium magnets? Are they a Martian metal that came from outer space? To your disappointment, there's no such conspiracy theory. It is a rare earth magnet - an alloy including elements such as Iron, neodymium and boron. The chemical formula for this unique alloy is Nd2Fe14B. Often one is likely to find crystalline structures in tetragonal shape in terms of a neodymium magnet. This alloy is well the strongest permanent magnet available

This neodymium magnet compound is discovered by General Motors Corporation, China Academy of Science and Sumitomo Special Metals in 1982. At that time there was a great are looking for a suitable cost effective replacement SmCo permanent magnets due to its rising costs.

Today the these magnets are made via two production forms - sintered (powdered) and bonded magnet process. Approximately 45000 to 50,000 a lot of sintered magnets are produced yearly in comparison to 5500 tons of bonded magnet. The gap can be attributed to the supply and demand issue. The remanence i.e. the way of strength of magnetic field of a magnet is high for any sintered magnet. The Curie temperature (named after Pierre Currie, famous French physicist and husband of Marie Curie) could be the temperature at which the magnet loses its magnetism is same for both forms of neodymium magnets (approx 310 to 400o C). The Curie temperature of those magnets can be increased to 800o after alloying these with terbium and dysprosium.

The neodymium rare earth magnets are also known as neodymium iron boron magnets. No prizes for guessing why. Other popular names where it is referred by is neodymium rare earth magnets. The aspect about these magnets is because have an exceptionally high resistance to get demagnetized. This makes them very helpful for various mechanical as well as industrial applications. Like a small size magnet form is incredibly powerful, the neodymium magnets are portable. And in all probability the best aspect is that they are affordable which makes them perfect for lab experimentation and research. It's possible to easily find neodymium disc magnets and neodymium ring magnets.

The side effects of these magnets is because are very corrosive anyway; hence need to be handled with absolute caution. A number of these magnets in combination with little care can simply snap your finger. So that it needs to be used with caution and a spotlight. They can catch fire at high temperatures but work nicely in conditions where low climate is maintained.

There are immense reason for neodymium rare earth magnets. They are utilized in healthcare industry (in MRI machines), in security equipment such as alarms and switches, to harddrive of computers.
