2021-11-03

Neodymium magnet, also known as neodymium iron boron magnet, with the chemical formula of Nd2Fe14B, is an artificial permanent magnet, which has the strongest magnetic force so far.

Neodymium magnet was invented in 1982 by Shinzo Sasakawa of Sumitomo Special Metals Co., Ltd. according to its chemical formula, it is mainly composed of neodymium, iron, boron and other chemical elements. It is possible to replace traditional pure iron magnets, aluminum nickel cobalt alloy and samarium cobalt magnets in many fields, such as motors, instruments and meters, automobile industry, petrochemical industry and magnetic medical and health care products. It can produce various shapes: such as disc magnet, ring magnet, rectangular magnet, arc magnet and other shapes of magnets.

Neodymium magnets with strong magnetism are widely used in electronic products, such as hard disks, mobile phones, headphones and so on.
