an electromagnet performs its magnetic property only when it is conducted with currents(either direct current or alternating current) while the permament magnet is the kind of material which show its magnetic property in the common situation.
It requires a current through a coil of wires.
a electromagnet is bigger than a bar magnet

a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
