Was repeatedly forced to stop the train leave for spring and fast in April, today, Ricky small make up to give everybody the electric magnet, many people saw electric magnet would immediately think of electromagnet, which make them confused. First of all let us distinguish the difference between electric magnets and electromagnets: 1, electrical magnet is can represent all audio sound appliances and through magnetic force after turning on the power supply is needed to work on this a series of electrical equipment. Below for a big circle 2, ferrite permanent magnet and electromagnet is a kind of electricity to generate electromagnetic device. It is generally through the winding on the outside of the core power to match with the conductive lines, circling it can during a conductor has current can have magnets have magnetic, it is also called the electromagnet. It is special in, electricity is magnetic and will not produce magnetic without electricity. And a fault current, produced by the magnetic also will disappear. Therefore, the electromagnet is widely used in large cranes, maglev train, the electromagnetic relay and so on! Electric magnet as long as it is, then basically can contain. As we often use the stereo and speakers, refrigerators, microwave ovens, television, washing machines, DVD, VCD, electric fan, tape, computer, etc. , these appliances are inside contain magnets. And many electrical appliances internal chip is also a magnetic! So you can't put strong magnet with a strong magnetic things such as these on the side of the chip and its appliance, because produce demagnetizing effect, to the normal chip and its electrical appliances can't work. One of the most typical example is that many of our membership card is belong to the electric magnetic card, people often put electric magnetic card and the magnet together, finally, he was degaussing electric magnetic card, not normal to use! Article electromagnet and the difference between the electric magnet xiaofu by magnet manufacturer original share, pay more attention to magnet knowledge welcome!
