Dynamo for the convection electric field and the Region-1 field-aligned currents reproduced by the global MHD simulation. The dynamo currents shown with the red lines are diamagnetic currents generated by the pressure force of hot plasma (left) poleward of the cusp region, (right) flowing across the magnetic field lines and driving the R1 FACs down the magnetic field lines into the ionosphere as shown with the black lines. The ionosphere is assumed at 3.5 Re in the simulation. (from Fig. 8 of Tanaka 1995)
