Question

wat is electromagnet?????​

Answer 1

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. An electromagnet works because an electric current produces a magnetic field.

Answer 2

An electromagnet is a soft metal core which is made into a magnet by passing electricity through a coil wounded around it.
