Typical spiral including a turbulent field. Upper-left panel: the contributions to the magnetic velocity (solid) are from the total field of B_ϕ (dotted), B_r (dashed), B_z (dash dot dot), and the B_rB_z term (dash dot) of the regular field only. Upper-right panel: radial dependence of the pitch angle for the regular field (solid) and the anisotropy q_iso of the turbulent field (dotted). Lower-left panel: radial profiles of total magnetic field components B_ϕ (solid), B_r (dotted), and B_z (dashed) (the last two components are almost identical). Lower-right panel: rotation modified by the Lorentz force (solid) and from the gravitation only (dotted).
