Figure \(\PageIndex{1}\): Hall Effect measurement setup for electrons. Initially, the electrons follow the curved arrow, due to the magnetic force. At some distance from the current-introducing contacts, electrons pile up on the left side and deplete from the right side, which creates an electric field \(\xi_y\) in the direction of the assigned VH. VH is negative for some semi-conductors where "holes" appear to flow. In steady-state, \(\xi_y\) will be strong enough to exactly cancel out the magnetic force, so that the electrons follow the straight arrow (dashed).
