Demonstration: This shows what happens when you have alternating magnetic fields between materials. A magnetic field is partially block by a thick piece of aluminum. The coke can also has a magnetic field with a direction opposite of the electromagnet. What happens is that the coke can being so thin begins to demagnetize as the electromagnet 's B field reaches maximum. The aluminum block being thicker become magnetized with a B field direction opposite of the electromagnet's field. The magnetization of the thick aluminum block causes an attraction force between the block and the can. This then causes the can to spin in the direction of the aluminum block's B field.
