In this experiment, the battery supplies the current to the copper wire via paper clips. Due to the current passing through the wire coil, the coil becomes an electromagnet with a north/south pole. Having the magnets on the battery causes the poles of the magnet and the coil to attract/repel. When the coil is spun, the opposite poles attract while the like poles repel simultaneously, causing the coil to spin continuously. During the experiment, the paper clips will heat up due to the resistance in the copper wire. The spinning of the coil causes torque, which causes more spinning.
