An electromagnet with soft iron core is temporary magnet.

Question

Verified by Toppr

Answer 1

The soft iron inside the coil makes the magnetic field stronger because it becomes a magnet itself when the current is flowing as compared to steel.Soft iron is said to form a temporary magnet. So, soft iron core is used in Electromagnet and not Steel.

Answer 2

Draw a circuit diagram to show how a soft iron piece can be transformed into an electromagnet.

You are given two similar bars.One is a magnet and the other is of soft iron.How will you distinguish and identify them?

Soft iron can be easily magnetised and demagnetised.

Core of an electromagnet must be of soft iron but not steel. Justify it.
