Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal composed of neodymium, iron, and boron (Nd2Fe14B). In 1982, Masayoshi Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this kind of magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the melt-spinning process, which can prepare NdFeB magnets. This kind of magnet is a permanent magnet whose magnetism is second only to that of an absolute zero degree holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. Stick NdFeB Magnet is your good choice.
