What is an electromagnet short answer?

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.

What is an electromagnet very short answer?

Definition of 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 explain with diagram?

The insulated copper wire is warpped 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.
