Question

an electromagnet works only in the presence of electricity​

Answer 1

An electromagnet behaves like a standard magnet but only with an electrical influence. When the power generation to an electromagnet stops, the production of the magnetic field also stops. Thus an electromagnet is a temporary magnet and not a permanent magnet.
