Answer:
(3) A light bulb is not a component of an electromagnet.
Explanation:
A coil of insulated wire is twisted around a piece of magnetic material, such as soft iron, to create an electromagnet.
As long as the current flows through the wire, the magnetic substance acts as a magnet.
The magnetic field strength of the coil is increased by the iron core.
An electromagnet is made up of three major components.
They are (a)the iron core (b)copper wire and (c) an power(electricity) source
