Fig. 4 — (A and B) Magnetic field configurations from two-dimensional axisymmetric simulations incorporating all nonideal MHD effects. (A) Vertical field aligned with disk rotation. (B) Vertical field anti-aligned with disk rotation. Shown in color is the scaled toroidal field strength (B_ϕ/Gauss)∙ (R/AU). Black contours mark poloidal field lines, and white contours mark the total field strength in Gauss. (C and D) Vertical profiles of the radial, azimuthal, and vertical components of the magnetic field at 7 AU from the simulations shown in the top panels for vertical field aligned (C) and anti-aligned (D) with disk rotation. Simulations from (79) after evolving about 1200 and 1800 years.
