Neodymium magnet (Neodymium magnet), also known as Nd2Fe14B magnet, is an artificial permanent magnet with the strongest magnetic force up to now.
Neodymium magnet was invented in 1982 by Sumitomo Special Metals Co., Ltd. Kenji Sakawa and others. Its chemical formula shows that it is mainly composed of neodymium, iron, and boron. Neodymium magnet with strong magnetism is widely used in electronic products.
Nowadays, Neodymium magnet is rapidly developing and widely used. It is possible to replace traditional pure ferromagnets, Al-Ni-Co alloys and samarium-Co magnets in many fields, such as motors, instruments and instruments, automotive industry, petrochemical industry, and magnetic health care products. It can produce various shapes: disc magnets, ring magnets, rectangular magnets,
arc magnets and other shapes of magnets.
Neodymium magnet exists in everyday electronic products, such as hard drives, mobile phones, headphones and so on. Neodymium magnet plays a more and more important role in the professional audio field. Because Neodymium magnet has a small volume, lightweight, and large magnetic flux. So it is very suitable for professional stage amplification and large stadium amplification.
