The Hall effect is a phenomenon observed in electrical conductors and semiconductors when they are placed in a magnetic field perpendicular to the direction of an electric current. It was discovered by Edwin Hall in 1879. When a current-carrying conductor is subjected to a magnetic field, the motion of the charged particles (such as electrons) in the conductor is affected by the magnetic field.
