Adavantages of electromagnet over a permanent magnet

Answer 1

Answer:

Hope this answer helps

Explanation:

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Answer 2

Answer:

*In an electromagnet the magnetic field can be changed by changing the current flowing through it.But in an permanent magnet this cannot be changed.

*The direction of the magnetic field can be changed in electromagnet.But in permanent magnet this cannot be changed.
