What Is a Neodymium Magnet?

Neodymium magnet is also called NdFeB magnet . It is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). In 1982, Sato Makoto, a special metal of Sumitomo, discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet was greater than that of samarium-cobalt magnets, and it was 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 produce NdFeB magnets. This kind of magnet is the permanent magnet with the second highest absolute magnetism. It is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, headphones, and battery-powered tools.

Neodymium magnet is also called NdFeB magnet .

NdFeB is divided into sintered NdFeB and

NdFeB, also called NdFeB magnet , is a tetragonal crystal formed of neodymium, iron and boron (Nd ₂ Fe ₁₄ B). A neodymium magnet was discovered in 1982 by Masato Sagawa of Sumitomo Special Metals, Japan. The magnetic energy product (BH _max ) of this magnet was greater than that of samarium cobalt magnet, and it was the substance with the largest magnetic energy product at that time in the world. Later, Sumitomo Special Metals developed the powder metallurgy process. General Motors has successfully developed a melt-spinning process that can produce neodymium-iron-boron magnets. This magnet is the most magnetic permanent magnet today, and the most commonly used rare earth magnet. ^[1]
