Initial magnetic field strength B_init generated by the small-scale dynamo (top panel) and the final magnetic field strength B_f generated by the α–Ω dynamo (middle panel) for a 10⁵M_⊙ star with an accretion rate of 10^-1M_⊙ yr^-1. In the bottom panel, we show the orbital timescale, the growth time of the α–Ω dynamo, and the ordering timescale. The left panels show the atomic cooling regime in the inner parts of the disk, while the right panels show the H₂ cooling regime on larger scales.
