Instantaneous snapshots of the surface radial magnetic field B_r at r/r_o = 0.95 (top) with the same fields filtered to l ≤ 5 (bottom) for different parameters: (a,d) N_ρ = 6, Ra/Ra_cr = 32, multipolar fields; (b,e) N_ρ = 6, Ra/Ra_cr = 16, quadupolar waves; and (c,f) N_ρ = 6, Ra/Ra_cr = 32, during dipole period. The color maps in panels (a-c) were saturated to 0.5|B_r|^max to highlight the spatial structure of magnetic features.
