The difference between electromagnet and electrical magnet

Electrical magnets represent all electrical appliances that can emit audio sounds and a series of electrical items that need to be powered through magnetic force to work.

An electromagnet is a device that conducts electricity to generate electromagnetism. It is generally formed by winding a conductive line that matches its power on the outside of the iron core. It can have the magnetic properties of a magnet when there is current in the wire. It is also called an electromagnet. Its special feature is that it is magnetic only when it is electrified, and it will not produce magnetism when it is not electrified. And once the current is cut off, the magnetism generated by it will disappear inside. Therefore, electromagnets are widely used in large cranes, maglev trains, electromagnetic relays and so on.

As long as the electrical magnet is electrical, it will basically contain it. For example, the stereos and speakers we often use, refrigerators, microwave ovens, TVs, washing machines, DVDs, VCDs, electric fans, tapes, computers, etc., all of these appliances contain magnets. Moreover, the internal chips of many electrical appliances are also magnetic. Therefore, strong magnets and other strong magnetic objects cannot be placed on the side of these chips and their electrical appliances, because it will produce a degaussing effect, which will cause the chips and their electrical appliances to not work normally. The most typical example is that many of our membership cards and meal cards are electromagnetic cards. People often put electromagnetic cards and magnets together, and in the end, his electromagnetic cards are degaussed and cannot be used normally.
