There are two ways to achieve the kind of functions: a magnet, is to use an electromagnet 2, is the use of two magnet misalignment, you should have seen the first two kinds of methods are used to achieve. I.e., two parallel bar magnets suction together (side by side as two chopsticks in a), which is equivalent to a magnet (one of the N and S poles respectively attracting the other one of the S and N poles), when the When the lever is pushed to the side of the other side, and at this time occurs in a two bar magnets dislocation (block N and S poles juxtaposed against another piece of the N and S poles) Decorative magnet block magnetic magnet disappears, you can remove the plate. Next five years, industry variables increase over the past decade, the expansion of China's magnetic materials industry capacity are very fast, thanks to the common development of domestic and foreign enterprises. On the one hand, domestic production capacity continues to increase, which also emerged Zhong Ke San Huan, Ningbo Yunsheng, Hengdian East magnetic, and other companies such Tiantonggufen technical and scale advantages. On the other hand the heart-shaped magnet, the magnetic material manufacturing enterprises in developed countries, due to the high cost of domestic production, the production capacity and technology transfer to the more backward areas, and both the costs and advantages of Chinese industry chain has become the first choice. According to incomplete statistics stereo magnet, has been cast in the mainland factories or cooperation of well-known companies, including Japan TDK, FDK, EP Juan SON, Hitachi Metals, Sumitomo, Korea, pear, and three European PHILIPS, VAC, EPCOS US ARNORD, MAGNEQUENCH like.
