9 FIG. 10: The components (left: radial component  right: azimuthal component) of the magnetic pattern in the AMRI domain (fast rotation) for β = 10 . Top: Re = 150   Ha = 50 ( minimum); bottom: Re = 200   Ha = 80 . The fields are normalized with B$_{in}$ . µ B = 1   Pm = 1 . FIG. 11: Components of the magnetic pattern (left: radial component  right: azimuthal component) for TI (slow rotation). Re = 30   Ha = 130 . Top: β = 2   Bottom: β = 10 . The fields are normalized with B$_{in}$ . µ B = 1   Pm = 1 .
