Hall Effect

(voltage generated by interacting current and magnetic field)

The Hall Effect is a voltage difference generated by magnetic field lines and a current not in parallel to the field lines. The voltage difference is perpendicular to both.

The Hall effect in Plasma may be relevant in Star Formation (SF) and in the behavior of Circumstellar Disks. It is thought to be a factor in the reduction of angular momentum of gas to allow it to move inward.
