What is an electromagnet Class 10?

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 electromagnet how it works Class 10?

An electromagnet works on the principle of the magnetic effect of electric current. It is formed when a strong magnetic field is produced inside a solenoid to magnetise a piece of a magnetic material like soft iron. Electromagnets are made out of a coil of wire (wire curled in series).

What is an electromagnet easy?

Electromagnets. When an electric current flows in a wire, it creates a magnetic field around the wire. … A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.

What is an electromagnet for 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.

What is an electromagnet for Class 6?

An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
