This effect is exhibited in an oscillatory pattern in the Shubnikov de Haas effect, and its magnitude can be measured by connecting symmetrical contacts in the van der Pauw method. A secondary current can be induced in a circular metal disk in one variant for it named for Corbino. Klaus von Klitzing discovered integral changes in resistance in a MOSFET, which is the "quantum" form of this and it can be used to show that electrons serve as charge carriers. For 10 points, name this effect wherein a magnetic field applied perpendicularly to the flow of a current results in a potential difference in a transverse direction
