Law of electromagnetism that describes mathematically the magnetic force between two electric currents. It was named after A.-M.
Ampère, who discovered that such forces exist. If two currents flow in the same direction, the force between the two wires is attractive; if they flow in opposite directions, the force is repulsive. In each case, the force is directly proportional to the currents.
