Rare Earth Magnets are including Neodymium(Nd) -Iron(Fe)-Boron(B) types and Samarium(Sm)- Cobalt(Co) classes. The most commonly produced material is neodymium-iron-boron (NdFeB). This group of magnetic materials provides the highest available magnetic energies of any material. NdFeB magnets allow small shapes and sizes with high magnetic fields. En1
The NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Compared with the cast Al-Ni-Co permanent magnet material and the ferrite permanent magnet material, NdFeB has a very high magnetic energy product and coercive force, and can absorb a weight equivalent to 640 times its own weight.
