Question:-
What is an electromagnet?Mention two properties of an electromagnet.​

Answer 1

Explanation:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.

properties

(i) An electromagnet is temporary in nature. (ii) An electromagnet is made of a soft iron core. (iii) The magnetic field strength can be changed. (iv) An electromagnet can be easily demagnetized by switching off the current.

$\huge\bold\pink\bigstar{Answer}$

A magnet produced by passing an electric current through a coil wound around a soft iron core is called electromagnet.

• An electromagnet 's strength depends on the number of turns of wire and the amount of current passing through it.
• An electromagnet is not a permanent magnet.
• Its Magnetism lasts only while a current passes through its coil.
