Answer:
An electromagnet can be made in the following two shapes:
1. I-shape or bar magnet.
2. U-shape or horse-shoe magnet.
The principle behind making both the magnets is the same. An electromagnet can be made by winding an insulated copper wire over a piece of soft iron in U-shape or a solenoid.
