Parsec-scale obscuring accretion disk with large scale magnetic field in
  AGN
  Magnetic field dragged from the galactic disk along with inflowing gas can
provide vertical support to the geometrically and optically thick pc-scale
torus in AGN. Using the Soloviev solution initially developed for Tokamaks we
derive an analytical model for a rotating torus supported and confined by
magnetic field. We further perform three-dimensional magneto-hydrodynamics
simulations of X-ray irradiated pc-scale magnetized tori. We follow the time
evolution and compare models which adopt initial conditions derived from our
analytic model with simulations in which the initial magnetic flux is entirely
contained within the gas torus. Numerical simulations demonstrate that the
initial conditions based on the analytic solution produce a longer-lived torus
and one which produces obscuration which is generally consistent with observed
constraints.
