Experiments to Determine the Effect of Magnetic Field on Floating Potential in Glow Discharge Plasma System

Abstract

In this experimental work, the variations in floating potential are discussed by the experimental research on plasma physics. The variations in floating potential with respect to the discharge voltage in the glow discharge plasma system are discussed. The variations in floating potential with respect to the distance of bar magnet from cathode are experimentally studied and discussed. The variations in floating potential with respect to the chamber pressure are experimentally studied. These experimental results may be useful for the applications in basic sciences and in technology.
