Why are electromagnets made of soft iron?

This is because soft iron has the property of losing its magnetism(or is able to be demagnetized) very quickly.

An electromagnet works in this way: when current flows through it, it becomes magnetized, and immediately current stops flowing, it loses its magnetism.

Hence, soft iron cores are the ideal material for this application.
