Question

Mention three uses of magnet and electromagnet

Answer 1

Dear Student,

Magnets have their lot of applications in the daily life. The major 10 uses of the magnets are as follows:

1. They are used to construct the electrical motors and the generators which convert the electrical energy into mechanical energy and vice verse.
2. They are also used in the speakers which can convert the electrical energy into sound energy.
3. They are used in the electrical bells.
4. They are used in the Maglev trains. In the Maglev trains, the super conducting magnets are used on the tracks on which the train floats. These types of the trains are working on the repulsion force of the magnets.
5. They are also used to sort out the magnetic and non magnetic substances from the scrap.
6. They are used in TV screens, computer screens, telephones and in tape recorders.
7. They are used by the candy or cold drink vendors to separate the metallic cap from the lots.
8. They are used in cranes.
9. They are used in the refrigerators to keep the door close.
10. The most important use of the magnet is the magnetic compass which is used to find the geographical directions
11. Electromagnets are used in all kinds of electric devices, including hard disk drives, speakers, motors, and generators, as well as in scrap yards to pick up heavy scrap metal. They're even used in MRI machines, which utilize magnets to take photos of your insides!

12. Motors and generators are vital to everything we do in the modern world. A motor takes electrical energy and uses a magnet to turn that electrical energy into motion.
