The in???uence of a transverse magnetic ???eld on a subnormal glow discharge in air

摘要

In subnormal glow discharge under d.c. excitation at different pressure in a varying transverse magnetic ???eld (0 to 30 G) some measurements have been carried out for various initial average tube currents. The voltage across the discharge increases and average tube current and residual current decreases in the magnetic ???eld. With the help of Beckmana€?s expression [4] for the axial ???eld and the electron density distribution in a transverse magnetic ???eld the observed variation of current and voltage can be satisfactorily explained. The variation of axial electric ???eld with transverse magnetic ???eld can be represented to a fair degree of accuracy by the derived equation. The behaviour of residual current with magnetic ???eld has been observed in these oscillations.
