Question

Give one word for the following.

A temporary magnet depends on the magnetic effect of the current.

Answer 1

1. An electromagnet is a temporary magnet.
2. An electromagnet behaves like a bar magnet.
3. When an electric current is allowed to pass through it, one end behaves like a north pole and the other end like a south pole.
4. Polarity of the ends depends on the direction of the current.
5. Strength of the magnetic field depends on the number of turns and electric current flowing in it.

Hence, an electromagnet is a temporary magnet that shows magnetism when an electric current is flowing through it.
