Neodymium iron boron, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). The magnetic energy product (BHmax) of this magnet is greater than that of the samarium cobalt magnet, which was the largest magnet in the world at that time. Neodymium magnet is the most powerful permanent magnet and the most commonly used rare earth magnet. As a part of the rare earth magnet family, neodymium magnets have good magnetic performance, which makes them be they the first choice for many consumer, commercial, industrial and technological applications.
