General Description for NdFeB Rare Earth Magnets
Rare Earth Magnets include 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. Energy product ranges from 26 MGOe to about 45 MGOe
