Top (top panel) and lateral (bottom panel) views at the distribution of current density at t = 618.6 s for the first numerical experiment when plasma is rotated clockwise over the negative polarity N1. The arrows show the current density direction, the size and color of the arrows indicate the current density amplitude. Also shown are the Z component of the magnetic field at the bottom of the simulation box and the corresponding magnetic field lines. The lateral view is along the positive X axis.
