Abstract
The motion of the cathode spot of a mercury arc was observed under various transverse magnetic fields, arc currents, and inert gas pressures. With no inert gas, the retrograde velocity increased as the magnetic field strength increased. Addition of an inert gas at low pressures reduced the retrograde velocity and at higher pressures caused a forward (direction of magnetic force) motion.Keywords
