Region 2 currents originate from polarization charges (positive/negative at dusk/dawn) created by hot plasma particles convecting sunward due to the dawnâdusk electric field and gradient-curvature drifting azimuthally charged particles (electronsâeastward, ionsâwestward).

CURVATURE DRIFT As is easily demonstrated, the quantity is a vector that is directed toward the center of the circle that most closely approximates the magnetic field-line at a given point, and whose magnitude is the inverse of the radius of this circle. o Right is a cross-section of a tokamak magnetic field. The particles overshoot the field line in the E × B drifting frame as shown here, gaining energy by the cross-tail electric drift if that is duskward.
