An exhibit at the Exploratorium of San Francisco. Two coils of wire are connected with magnets inside them. As one coil is moved, an electric current is created by the magnet and travels through the coil to the other coil. The current in this second coil creates a magnetic field that interferes with the magnet near it. This interaction causes the second coil to move even though it hasn't been touched!
