Fig. 12

Radial magnetic field close to the surface at time t = tap for the first 2 cases shown in the previous figure for Re = 2 × 104 (top panels) and for cases at Re = 4 × 104 (bottom panels) and with Lo = 3 × 10-3 (left) and Lo = 10-2 (right). The left panels correspond to the cases where the instability reaches the level of energy of the axisymmetric mode.
