Imposed initial (fossil) magnetic fields in our simulations. The arrows represent the poloidal magnetic field lines, and the colormap the intensity of this component. Dipole A and Dipole B* are aligned to the rotational axis (β = 0°), and as an example of a misaligned dipole an inclination of β = 30° was added in Dipole B. The last panel corresponds to the initial snapshot of run DipB (Dipole B + MHDr2).
