In this edition of How Stuff Works you will learn how electromagnets work. You will also have a chance to try several experiments with an electromagnet that you create yourself. Since you have played with magnets you know that all magnets have two ends, normally marked north and south . You know that magnets attract things made of steel or iron.
Opposites attract and likes repel.
So if you have two bar magnets with their ends marked north and south, then the north end of one magnet will attract the south end of the other. Inc. All rights reserved.
