Classification magnet magnet can be grouped into "permanent magnet" and "non-permanent magnets." Permanent magnet may be a natural product, known as lodestone, also be made artificially produced (the strongest magnets are neodymium magnets). The non-permanent magnets, magnetic only under certain conditions there, usually in the form of an electromagnet to produce, i.e. the use of electric current to strengthen the magnetic field. Magnet internal magnetic molecules into non-magnetized magnet and the magnet (molecular magnets doctrine) is not a regular array of magnets mayong tool manufacturers, after the process of magnetization of the magnetic elements arranged in the rules will be. At this point magnet GAOBU tool manufacturers, N pole and the S pole magnetic molecules will be facing in the same direction so that the magnet has a magnetic and become magnets. At the same time, the presence of the opposite poles of the magnetic poles and an equal amount on the same magnet. 3. Q: What factors affect the price of the magnets have? A: 1) Material costs: higher performance requirements magnet tool manufacturers, the higher the cost, such as NdFeB magnets, N45 N35 price is far higher than the price; 2) the processing costs: the more complex the shape magnet houjie tool manufacturers, processing costs The higher; more stringent tolerances, higher processing costs; the smaller the volume, the higher the processing costs. 4. Q: What kind of surface magnetic field strength up? A: The same shape, the same size as the surface magnetic field strength of the magnet NdFeB followed in descending sorting> SmCo> Alnico> Ferrite> Rubber magnets. Examples: Cylindrical D10x5mm NdFeB: 4,200 gauss samarium cobalt: 3,300 Gauss Ferrite: 1,200 gauss magnetic data table above are for reference only.
