Answer 2

Electromagnet :-

An electromagnet is a temporary magnet constructed by winding insulated wires around a soft iron piece (called core) and passing current through the wire.

Generally two types of electromagnets are used: Bar electromagnet and U-shaped electromagnet.

Electromagnet loses its properties soon after the current is turned off. Field lines of a bar electromagnet are shown in the diagram.
