⠀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 centre of the coil.⠀⠀⠀⠀⠀⠀⠀⠀

Answer 2

˙❥˙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 off electricity.
