Sumitomo Special Metals, the Nd2Fe14B magnet is the most widely used rare-earth magnet due to its superior magnetic properties. Neodymium magnet is today’s super-strong permanent magnet, and its properties continue to be improved.
Neodymium magnets are used in a wide variety of applications from electric vehicle motors to sensors; from hard disk drive actuators to magnetically coupled pumps. Many devices that now use a permanent magnet can be made smaller, with more power, when designed with a neodymium magnet. NdFeB was invented in the early 1980s.
