Question

advantage of electromagnet

Answer 1

it is stronger and better than a permanent magnt

he 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

In an electromagnet, the magnetic field can be quickly changed by controlling the amount of electric current in winding.
