Question

Which property of soft iron makes it useful for preparing electromagnet ?

Answer 1

Soft iron has very high permeability, which means, the magnetism is high even for a small magnetic field.

Also, soft iron turns intoa magnet itself as soon as electricity is passed through it and loses its magnetic properties as soon as the current stops flowing.

Thus, with a switch of a button, the electromagnet can be switched off as the flow of electricity is switched off. this explains that soft iron has less rentivity which makes it ideal to form a core of electromagnets.
