Answer:
An electromagnet is a magnet that consists of a piece of iron or steel surrounded by a coil. The metal becomes magnetic when an electric current is passed through the coil.
Explanation:
An electromagnet is a temporary magnet formed by winding a coil of wire round a piece of soft iron, and passing an electric current through it.
The electricity magnetizes the electromagnet, and when the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage.
The electromagnet provides the driving force to close the contacts, which are the current carrying part of the contactor.

Answer:
Explanation if you are asking about electromagnetic wave then it the specific type of wave containing magnetic and electrical fluctuating components ,or of you are asking about electromagnet then it a type of magnet that works when a certain amount of current is passed throught it ,specific meterial are used for it like soft iron
