We observe an increase in plasma density and a significant reduction in fluctuations with bias electrode in a pure toroidal plasma having no poloidal magnetic field. The improved toroidal plasma behavior is found to depend upon the radial currents driven by positive biasing of a ring electrode. Although biasing establishes a radial electric field at the edge, we see suppression of fluctuations and density rise in the central core region of the plasma.
