Additional information

1. Electromagnets are based on the magnetic effect of current.
2. An Electromagnet shows magnetic properties only as long as the electric current flows through the coil.
3. Electromagnets are temporary magnets.
4. Electromagnets of very high strength can be made easily.
5. An Electromagnet is usually prepared by winding a large number of turns of an insulated copper wire on a soft iron core.
