Electromagnets In the late 18th and early 19th centuries, several different important discoveries were made related to magnetism and electromagnetism. Danish physicist Hans Christian Oersted discovered that a magnetic field is produced around a wire when there is electric current in a wire. A compass needle will move when placed next to a current carrying wire. French scientist Andre Marie Ampere discovered that there are magnetic forces between two wires carrying current. The direction of force depends upon the direction of the current. English scientist Michael Faraday discovered that when a magnetic field is moved near a wire, electric current is produced in the wire.
