I have read that soft iron is suitable for making a permanent magnet. Because it is required for permanent magnet to have high coercivity and high retentivity.

Same text also said earlier that soft iron has low coercivity and low retentivity and is very useful in making solenoids cores.

What is the actual answer and also the reason?

1 Answer 1

Soft iron has a high retentivity (or remanence) but a low coercivity. Therefore it is not a suitable material for making permanent magnets
