ElectromagnetsIn the late 18th and early 19th centuries, several different important discoveries were made related tomagnetism and electromagnetism. Danish physicist Hans Christian Oersteddiscovered that a magnetic field is produced around awire when there is electric current in a wire. A compass needle will move when placed next to acurrent carrying wire.French scientist Andre Marie Amperediscovered that there are magnetic forces between twowires carrying current. The direction of force depends upon the direction of the current.English scientist Michael Faradaydiscovered that when a magnetic field is moved near a wire,electric current is produced in the wire.
