Electromagnets:
An Electromagnet is a temporary magnet, caused by a current flowing around a metal core (usually iron). A solenoid as a coil of wire looped around an iron core. Ways to increase the strength of an electromagnet is to increase the number of loops in your solenoid, increase the current running through your wire, and add an iron core to the center of the electromagnet.

Electromagnets stop power surges. If a power surge happens at the wrong time, it can cause a house fire. By understanding electromagnets, we can understand how to prevent these fires.
