The effect of a deliberately imposed radial electric field on the plasma confinement characteristics in a tokamak has been studied. This field can trigger a transition to the Η confinement mode and back during ordinary ohmic heating. When the polarity of the field is reversed, the current flowing in the electrode-plasma-wall circuit changes significantly.
