Neodymium magnets for sale
Most of us use a neodymium magnet in a form or the other; we only don’t know that we do. There are so many uses and benefits of this amazing piece of human invention of which we are unaware of. One can possibly easily find a neodymium magnet in the hard disk of a computer, headphones, and loud speakers for starters. And these magnets are immensely powerful and let 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 isn’t any such conspiracy theory. It is just 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 relation to a neodymium magnet. This alloy is definitely 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. Then there was a great must discover a suitable cost effective replacement SmCo permanent magnets due to the rising costs.
Today the these magnets are manufactured via two production forms – sintered (powdered) and bonded magnet process. Approximately 45000 to 50,000 a lot of sintered magnets are produced annually 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 an magnet is high for any sintered magnet. The Curie temperature (named after Pierre Currie, famous French physicist and husband of Marie Curie) will be the temperature at which the magnet loses its magnetism is same either way forms of neodymium magnets (approx 310 to 400o C). The Curie temperature of those magnets can be increased to 800o after alloying them terbium and dysprosium.
The neodymium rare earth magnets are also known as neodymium iron boron magnets. No prizes for guessing why. Other popular names through which it is referred by is neodymium rare earth magnets. The aspect about these magnets is because have an exceptionally high capacity get demagnetized. This makes them very useful for various mechanical in addition to industrial applications. As a small size magnet form is very powerful, the neodymium magnets are portable. And in all likelihood the best aspect is because are affordable causing them to be perfect for lab experimentation and research. It’s possible to easily find neodymium disc magnets and neodymium ring magnets.
The negative effects of these magnets is because they are very corrosive naturally; hence need to be handled with absolute caution. Several these magnets used in combination with little care can easily snap your finger. In order that it needs to be used with caution and attention. They can catch fire at high temperatures but work well in conditions where low temperatures are maintained.
There are immense reason for neodymium rare earth magnets. You can use them in healthcare industry (in MRI machines), in security equipment such as alarms and switches, to hard drive of computers.
