Question

how a electromagnet works ?​

Answer 1

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

Answer 2

Answer:

We already know that an electric current has the ability to produce a magnetic field in a plane perpendicular to the direction of current flow. The electromagnet uses this principle. An electromagnet can be defined as a magnet which functions on electricity....
