Answer 2

$\bf{\underline{\underline \blue{AnswEr:-}}}$

It is a type of magnet in which the magnet field is produced by an electric current. An electromagnet requires a continuous supply of current to maintain the magnetic field. Electromagnet are widely used in switch gears such as relays and contactors. Electromagnets are also used as components of electrical devices such as motors and generators.

The magnetic strength of an electromagnet can be increased by:

• Wrapping the insulated coil around the soft iron core.
• Increasing the number of turns in the coil.
• Increasing the strength of the electric current flowing through the coil.
