  • Already an expert on magnets? Then skip to the “aluminum pie tin experiment” at 1:17 .

    Which materials are strongly attracted to a magnet? A cow magnet is used to try to pickup a rubber comb, a nail, a brass medallion, a piece of aluminum, plastic, copper pennies, a screwdriver, a piece of steel, some nickels (Canadian and United States), wooden dowels, paper clips, a washer and a brass object. Can you predict which objects the magnet will pick up? (Turn down the volume, and make your predictions as the magnet approaches each object.)

    It is common knowledge that magnets can pick up most materials made of iron. Less well known is that nickel and cobalt are also strongly attracted to magnets (like iron, they are ferromagnetic).

    What if we used a stronger magnet? A neodymium magnet still isn’t able to pick up a piece of aluminum, but it can interact with it (see video clip) ! As the strong magnet moves near the surface of the aluminum pie tin, it pushes against the electrons in the metal, causing eddy currents. Those currents create their own magnetic fields which interact with the magnet.
