What is electromagnet class 10th?

An electromagnet is a temporary magnet which behaves like a magnet when an electric current is passed through the insulated copper wire and loses its magnetism when current is stopped. It has a soft iron piece called the core with an insulated copper wire wound on it.

What is called electromagnet?

: a core of magnetic material (such as iron) surrounded by a coil of wire through which an electric current is passed to magnetize the core.

What is an electromagnet CBSE?

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. … The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron.

What is electromagnet Class 10 list any two uses?

(a) An electromagnet is a magnet that is created using an electric current, created by electricity. The two uses are: 1)Motors and generators. 2)Transformers.

What is a electromagnet Class 7?

Answer: An electromagnet is a coil of insulated wire wound around a piece of a magnetic substance such as soft iron. The magnetic substance acts as a magnet as long as the current flows in the wire.

How is an electromagnet made Class 10?

The insulated copper wire is wrapped on a soft iron piece. When current is passed through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.
