Query: Simulations of black hole accretion torus in various magnetic field
  configurations   Using axisymetric general relativistic magnetohydrodynamics simulations we
study evolution of accretion torus around black hole endowed with different
initial magnetic field configurations. Due to accretion of material onto black
hole, parabolic magnetic field will develop in accretion torus funnel around
vertical axis, for any initial magnetic field configuration.
