The Hall effect is when a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicular to the direction of current flow, a voltage, called Hall voltage, proportional to the magnetic field, and the current appears on the faces sides of the bar. This tension is proportional to the displacement speed of the charge carriers, which is considerably higher in semiconductor materials than in metal conductors.
