State two advantages of an electromagnet over a permanent magnet.

Solution:

Electromagnets have two advantages over permanent magnets:
(1) Electromagnets’ magnetic strength can be increased or lowered. But the same is not possible with permanent magnets.
(2) Electromagnets have a higher magnetic power than permanent magnets.
Electromagnets are more widely used than permanent magnets because of these advantages.
