What magnets are used for?

Answer 1

Some magnets are used to make electric motors and generators.Some magnets are used for car doors,door hinges,computers,hovers,blenders, CD players,washing machines, fax machines, escalators, elevalators,loud speakers,credit cards,tv,fridge doors,toys,jewelry, and elecric toothbrushes, magnets are used in junk yards to make new cars too,magnets are used in Roller Coasters.These are called electro magnets and you can turn them on and off.and they are also used in the new unistation 360 witch is awesome.

Answer 2

Commonest use - probably electric motors, also magnetic catches/latches. Also record-player cartridges, clamps for ferrous articles, cathode ray tubes (TV's), moving-coil meters, and zillions more uses.

Answer 3

There are surely millions of examples where magnets are used, but a few general statements can be made here. (Both permanent magnets and electromagnets are employed in the areas below unless otherwise stated. Also, there are sometimes other types of electronics that will perform the same function as the magnet examples below.)

1. Magnets are used in devices that generate electricity. These are known as generators or alternators. Cars use them to charge the battery and operate the electrical system. The giant power generation turbines at damns use electromagnets.

2. Solenoids are electromagnets and many switches employ then to turn things on and off. Doorbells do this as well as virtually any remote controlled valve.

3. Magnets attract things and pick things up. Electromagnets can pick of very heavy objects and most people have seen refrigerator magnets.

4. Magnetic domains are encoded in memory devices. Old magnetic tape had millions of small magnets. The magnetic strip on a credit card has magnets.

5. Changing magnetic fields with both and an electromagnet and permanent magnet operate speakers to produce sound.

6. AC Transformers are based on the changing magnetic fields of electromagnets.

Answer 4

to attract
