Question

what is electromagnet?give three uses of electromagnets

Answer 1

An electromagnet is a magnet that is created using an electric current, created by electricity. Since electricity can be turned on and off, so can an electromagnet. It can even be weakened or strengthened by decreasing or increasing the current.

Answer 2

Uses of Electromagnet:

• Electromagnet is used in the Electrical appliances to transfer the electricity and heat from one medium to other.

• Electromagnetically devices like Motors, Generators, Electric bells, Loudspeakers, Headphones etc.
• Data storage: Electromagnets are used for storage of data.
• MRI machines works on the basis of Electromagnetism.

• Electromagnetism is also used in Electric locks and Transformers.

• Magnetic lock that we see generally is based on Electromagnet principle.

• Communication devices like smartphones uses electromagnetic waves.
• Internet services provided through wireless medium works on the basis of electromagnetism.
• The data storage feature of any smart device uses only electromagnet. This helps to store data more efficiently and rapidly.

About Electromagnet:

Electromagnet is a magnet that runs on the electricity . Once, Any magnet supported metal is connected with Battery or cell, then that Metal gets the Electromagnetism. Like a permanent magnets which we see in our daily life; The power of Electromagnets can be also changed by simply changing the flow of electricity in the battery of cell.

An electromagnet works because an electric current produces a magnetic field. The wireless technology which we use nowadays also uses the Electromagnetism to make a wireless connection between two electronic devices.
