Abstract
AN impressed radial current and an axial magnetic field combine in the Corbino disk1 to induce a circulating component of current due to the Hall effect. Whichever sense the axial field may have, it is aided by the field of the circulating currents themselves, provided that the radial current is always inwards. This applies to a material with the normal sign of Hall coefficient for n-type conduction.
