Hengdian Kim Dae-magnetic magnets magnet factory ------- not human invention, a natural magnetite, first discovered and use magnets should be Chinese. Therefore, the "compass" is one of the four great inventions of the Chinese people. As for the ingredients that is iron, cobalt, nickel, etc. The atomic structure of special high-quality sticky magnets, atom itself has a magnetic moment of general confusion molecular arrangement of these minerals. Influence on each other nearly as magnetic magnetic zone .. but external forces (such as the magnetic field ) molecular orientation tends guided by consistent on the show magnetism. also known as magnetic iron cobalt and nickel are the most common magnetic material. Hengdian Kim Dae-magnetic solenoid factory ----- invention when the invention of the electromagnet was originally found in principle from the beginning of the electromagnet. In 1822, France's two physicists found 阿拉格 and 吕撒柯 principle of quality first solenoid magnet stick specifications, they found that if a piece of iron wire interesting laps during the test, and to wire for charging, that piece of iron wire was immediately surrounded it was magnetized. Quality sticky magnet suppliers, Beijing high-quality sticky magnets, Kim Dae-magnetic plant warm service is provided by a large magnetic Hengdian gold plant. Hengdian Kim Dae-magnetic Factory (www.jjdct.cn) strong, credible, Zhejiang Jinhua electronics, electrical equipment manufacturing industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Kim Dae-magnetic factory and you hand into the brilliant, for a better future!
