Time evolution of B_rms (left panel) and the vertical and toroidal fluxes (right panel) within the central disk for different initial field strengths and geometry. Darker lines represent a lower initial thermal plasma beta β_th within the center of the disk. The distinct levels of initial central plasma beta are (β_0, center = (10⁷, 10⁴, 1, 0.1)). We can see that for the low plasma beta cases (β_0, center ≤ 1) the magnetic field strength is quickly reduced at the beginning of the simulation, but eventually saturates at a level around 1 μG. This is a similar saturation level as the α_B = 0.25 simulations that grow from much weaker initial fields at the same resolution. Due to this outflow of magnetic flux, we can see that all simulations reduce to a similar oscillating flux within the central disk for the vertical and toroidal fields.
