A variant in metal disks in which secondary currents are produced is named for Corbino and along with sheet resistance, the van der Pauw technique measures this effect in semiconductors. While the associated voltage is normally negative, in some metals like beryllium it is positive meaning that the charge carriers involved are holes instead of electrons. A consequence of the Lorentz force, it occurs when the charge carriers interact with a perpendicular magnetic field. For 10 points, identify this effect where charge carriers of a current are pushed to one side of a conductor in a magnetic field creating a voltage.
