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 arc magnets allow small shapes and sizes with high magnetic fields1
Rare earth Neodymium magnet (NdFeB) is a high performance permanent magnet, which is produced by Neodymium Iron, Boron and some other rare earth elements, as the strongest permanent magnets discovered up to now, is preferred by permanent magnetic devices, due to its highly cost-effective performance based on rich rare-earth resources, manufacture i1
