The Corbino effect is a variant of this effect in a circular geometry.  This effect can be measured along with the resistivity and mobility using the van der Pauw technique.

The Corbino effect is a variant of this effect in a circular geometry.  This effect can be measured along with the resistivity and mobility using the van der Pauw technique.  When the collision frequency is much lower than the Larmor or cyclotron frequency, its namesake coefficient is one over the charge density.  The current definition of the ohm is based on a variant of this effect discovered by Klaus von Klitzing known as its integer quantum version.  The sign of the charge carriers in a current can be determined using, FTP, this effect in which a transverse voltage develops across a current-carrying conductor placed in a crossed magnetic field.
