Plots for PAD09 (left), PAD10 (center) and PAD09R (right). (a) ﹩| j| /| B| ﹩, viewed in the xz-plane at y = 15 Mm, at t = 70 time steps (1.4 rotations). (b) xy path of magnetic null point in time from t = 0 (black) to t = 200 (red) time steps. An animation of ﹩| j| /| B| ﹩ in the xz-plane at y = 15 Mm for the PAD09, PAD10 and PAD09 simulations from time step 0 to 200 is provided online.
