Axisymmetrized components of “tilt-corrected” magnetic field in run NS (a = 0) in the ﹩{\rm{log}}r-\theta ﹩ plane at t = 110,700 r_g/c, where we have drawn the density scale height ((H/r)_ρ, Equation (8)) in white. We identify a transition in magnetic topology near r ≈ 200 r_g. (a) The toroidal field is symmetric about the midplane at large radii and becomes roughly antisymmetric about the midplane at small radii. (b) The radial field is unstructured at large radii and becomes roughly antisymmetric about the midplane at small radi. (c) The polar field is unstructured at large radii and becomes roughly symmetric about the midplane at small radii.
