Some Aspects of Mean Field Dynamo Theory - Indico
... A dynamo can be thought of as a mechanism for “closing the loop” between poloidal and toroidal fields. Velocity shear (differential rotation) naturally generates toroidal from poloidal field. The α-effect of mean field electrodynamics can complete the cycle and regenerate poloidal from toroidal fiel ...

Hall effect
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.The Hall coefficient is defined as the ratio of the induced electric field to the product of the current density and the applied magnetic field. It is a characteristic of the material from which the conductor is made, since its value depends on the type, number, and properties of the charge carriers that constitute the current.
