Magnetic field vectors versus disk orientation. The magnetic field lines align with the disk between  ~1.0−1.5   t_ff. The image shows a volume plot of the density from an XZ perspective (top) and an XY perspective (bottom) at t = 1.5   t_ff. The magnetic field vectors are displayed as white arrows, where the field strength B typically ranges from 1−1000   μG. The X-axis is given at the bottom in units of parsec.
