Why would repel each other after magnet disconnected? Magnet manufacturers find a variety of magnet to do the experiment, the results show that the fracture surface magnetic bar magnets broke at the opposite (that appears synonym poles), two of the fracture surface are attracted to each other easily together; and after the ring-shaped magnet and cake at fracture fracture surface are mutually exclusive, hard to put the two are pressed together, even if they are hard to be with him, as long as the mechanical hand release, Xie Gang magnets, immediately will be open to each other, and one will be instantly reversed, the fracture surface at the poles seem to be of the same name. Annular or pie-shaped magnet fracture surface at mutually exclusive reasons: Because the two poles on the torus or round surface, namely the upper and lower surfaces of the N, S pole, after the machinery broke Shek Pai magnet, which is still up and down poles machinery used on both surfaces of the magnet, so there will be two poles in the vertical fracture surface at two locations, near the time when the fracture surface, corresponding to the upper and lower sides of the same name is Hengli machinery pole magnet, the magnetic poles of the same name is mutually exclusive , so it will have a fracture surface at the poles of the same name illusion. Once one piece upside down over and will be able to attract firmly together. Magnetic material is important electronic information materials, widely used in household appliances, automobiles, computers, communications, medical, aerospace, military and other fields. Generally based on the size of the material coercive force, the magnetic materials permanent magnetic materials and soft magnetic materials into two categories. Permanent magnetic materials can be roughly divided into carbon steel, aluminum, nickel and cobalt (AlNiCo) alloy, ferrite magnets and rare earth permanent magnet, such as several major categories. A variety of magnet performance parameters of different application areas have different emphases. Currently ferrite magnets permanent total output has accounted for more than 90% share. Soft magnetic material is divided into ferrite and soft metal, a larger share of the soft ferrite. In recent years, with substantial growth in the booming Chinese economy and the world needs China's magnetic materials industry ushered in tremendous opportunities for development, the world center of magnetic materials industry has moved to China, China's magnetic materials industry average annual growth rate of more than 20 %. 2005 global production was 910,000 tons ferrite materials, China's output of 45 million tons, accounting for 49.45% of global production. It estimated that by 2010, the global magnetic materials production will reach 1.42 million tons, of 55 million tons, accounting for 38.7 percent of global production.
