TH Magnets NdFeB magnets(Nd2Fe14B),the third generation of the permanent magnets,mainly made from Neodymium, Iron, Boron, Which has excellent properties of high remanence, coercivity, and Max.energy. So it is widely used in automobiles, motors, generators, electronic products, VCM, magnetic separators, MRI-medical equipment, holding systems, switches and ects.
