Have fun with magnets while you learn how we use them every day in every way. Did you know there are magnets in the computers we use to store information and in our stereo speakers to make sound? The fastest trains use magnetism to push, pull, and levitate. We use magnets for motors and generators. We also use magnets for many different medical purposes. Our own Planet Earth is one enormous magnet with unimaginable power. Learn how to make and use a compass. These experiments and activities will show you the power of magnetic force and how it works. Here’s an interesting thought… Without magnets the great voyages of discovery could hardly have taken place – Columbus, Magellan and the rest. The history of the world might have been quite different!
