Question

when will you use magnet in separation process?why is an electromagnet used to separate scrap iron object instead of permanent magnet?​

Answer 1

Answer:

We will use magnet for separation when one of the components of the mixture is attracted by the magnet and others are not.

An electromagnet is used instead of permanent magnet because permanent magnet loses its strength of attraction gradually over time whereas electromagnet doesn't.
