Neodymium :
NdFeB, the third generation of rare-earth permanent magnet, has high remanence, high coercive force, high-energy product and high performance/cost ratio.
Neodymium Magnets are easily formed into various sizes and widely used in many fields such as magnets for aviation, electronics, instruments, meters, machine and medical instruments. Neodymium metal is used extensively to produce Nd-Fe-B magnets, which have energy densities as high as 27 to 35 million gauss oersteds.
They are the most
compact magnets commercially available. It is especially suitable for the development of magnets for high-performance, compact and light products.
