Current density (left) and plasma flow vectors (right) in the kinematic torsional fan model. Plotted for B0 = L0 = j = b = 1, a = 4 and p = q = 1 (above), p = q = 2 (middle) p = q = 5 (below). The grey curve (red online) in the right-hand plots marks the boundary of the non-ideal region. The current density is plotted at z = 0, while the plasma flow is plotted in the plane z = 0.5.
