Neodymium magnet, also known as NdFeB magnet, is a tetetic crystal system made of Neodymium, iron and boron (Nd2Fe14B). In 1982, Sumitomo Special Metals’ Misaki Sagawa discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet was greater than that of a samarium cobalt magnet, making it the largest material in the world at the time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process and general motors successfully developed a melt-spinning process to make Ndfeb magnets. The magnet is now the second most magnetic permanent holmium zero magnets and the most commonly used rare earth magnet. Ndfeb magnets are widely used in electronic products, such as mobile phones, hard disks, earphones and battery-powered tools.
