Types of magnets: Shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, wafer magnets, bar magnets, magnetic frame magnets, attribute magnets: samarium cobalt magnets, ferrite magnets, AlNiCo magnets, FeCrCo magnets, industrial magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft magnets. Permanent magnets are combined with strong magnetism, so that the spin of magnetic substances and electron angular momentum are arranged in a fixed direction. Soft magnetism is the addition of electricity. When the current is removed, the soft iron will gradually lose its magnetism. Magnetic materials have also been widely used in the military field. For example, ordinary mines or mines can only explode on contact with the target, and thus have limited effect. And if sensor magnets are installed on mines or mines, since tanks or warships are made of steel, when they are close (without touching the target), the sensors can detect changes in the magnetic field and cause the mines or mines to explode, increasing the lethality.
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet. It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. : Bonded Neodymium magnets are prepared by melt spinning a thin ribbon of the NdFeB alloy. The ribbon contains randomly oriented Nd2Fe14B nano-scale grains. This ribbon is then pulverized into particles, mixed with a polymer, and either compression- or injection-molded into bonded magnets. In 2015, Nitto Denko Corporation of Japan announced their development of a new method of sintering neodymium magnet material. The method For sintered neodymium magnets, there is a widely recognized international classification. Their values range from 28 up to 52. The first letter N before the values is short for neodymium, meaning sintered NdFeB magnets. Letters following the values indicate intrinsic coercivity and maximum operating temperatures (positively correlated with the Curie temperature), which range from
