Question
For making a strong electromagnet, the material of the core should be:
Answer: Option A
:
A
The soft iron inside the coil makes the magnetic field stronger because it becomes a magnet itself when current is flowing through the coil.
Moreover, it loses its magnetism as soon as the current stops flowing. It forms a temporary magnet.In this way, the electromagnet can be magnetised and demagnetised by turning the electricity on and off.
