Toroidal magnetic field values along the disk surface (top) and along the disk height (measured from the disk equatorial plane) at R = 12R⋆ (bottom) are shown in terms of their dependence of stellar rotation rates. The values are averaged over 10 stellar rotation periods during the quasi-stationary states, in the cases with αm = 1 and B⋆ = 500 G (simulations b1, b5, b9, and b13). In black, green, blue, and red dashed lines we display the values for 0.05, 0.1, 0.15, and 0.2 of Ωbr, respectively. The black solid lines provide the reference for typical radial and vertical dependence.
