Magnetic Poles
Have you ever wondered exactly how that magnet sticks to your fridge? In this BrainPOP UK movie, Tim and Moby will fill you in on the basics of magnets and magnetism. The dynamic duo will tell you all you need to know, from the discovery of naturally occurring iron magnets thousands of years ago, to the electromagnets of modern times. See how our lives today are dependant on the electromagnets found in cars, electric motors, and practically every electronic device you can think of. You’ll learn what magnetic domains are and how they work, as well as why a compass needle always points north. Plus, you’ll discover what a magnetic field is, and how you can create one with an electric current and a loop of wire. Magnetism is such an attractive topic! |
