content: Replica of Ampere's 1820 experiment showing that a helix carrying current acts as a magnet.
label: Description (Brief)
content: After hearing of Oersted's findings in 1820, André-Marie Ampere of France discovered that if wire were coiled into a cylinder, it would behave in exactly the same manner as a magnet. Such a coil is called an electromagnet. Ampere found that if a free-moving coil were placed near a wire, an electrical current would make the coil turn at right angles to the wire. The coil acts exactly like the magnetized compass needle in Oersted's experiment.
