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.
