Angular momentum redistribution in the radiative zone and the tachocline region. Panels a) are summed over θ₁ = 60 and θ₂ = 90 (north pole), and panels b) are summed over θ₁ = 30 and θ₂ = 60 (mid latitudes). The different fluxes are averaged approximately over six rotation periods. From left to right, the three plots correspond to the instants used to make Figs. 6a, c and d. Our magnetic field does not initially change the angular momentum balance.
