Every electric appliance has its own electric magnet. Such as audio, speaker, refrigerator, microwave oven, TV, washing machine, DVD, VCD, fan, tape, computer and so on. A lot of internal chip of electrical appliance have magnetic. You can not put the things which own strong magnetic near electric appliance inorder to cause demagnetization effect and even make the chip and its electric appliance can not work normally. For example, many people is habit to put their membership cards with magnet, that is easy to make the cards demagnetized.



Electric magnet represents the appliances which can send audio sound. It can work after connecting the power supply. But electromagnet is a kind of device that is energized to generate electromagnetic. Electromagnet is winding conductive line through the core external. But it will own magnetic after the power is switched on. On the contrary, it is without any magnetic if there is no power. So electromagnets are widely used in large crane, telephone, maglev train, automation control equipment, packaging machinery, medical equipment, food machinery and textile machinery.
