Neodymium Iron Boron (NdFeB) magnets, a sort of Rare Earth magnet material, has the high remanence, high coercive force, high Maximum energy and is easily formed into various sizes, shapes. So they have been widely used in commercially available fields since the MID -1980s.

It can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 48MGOe, while the bonded form holds a lower energy product of up to 10MGOe. Furthermore, The majority of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction.
