Rare earth magnets
The general name for permanent magnets whose main components are metal alloys of iron group transition elements and rare earth elements. These magnets can be roughly divided by manufacturing method into sintered magnets and bonded magnets. There are two types of typical magnetic alloys, the Sm-Co family and the Nd-Fe-B family. Compared to other permanent magnets, ferrite and alnico, rare earth magnets have clearly superior residual magnetic flux density Br , coercive force HcJ , maximum energy product (BH)max , etc. They are used in many industrial products that are representative of contemporary society, from industrial motors to computers, appliances, cell phones, automobiles, etc. Rare earth magnets are becoming indispensable materials for smaller size and higher performance of such equipment and device.
