Abstract:
We discuss the effects of electric charging on the equilibrium
configurations of magnetized, rotating fluid tori around black holes of
different mass. In the context of gaseous/dusty tori in galactic nuclei,
the central black hole dominates the gravitational field and it remains
electrically neutral, while the surrounding material acquires some
electric charge and exhibits non-negligible self-gravitational effect on
the torus structure. The structure of the torus is influenced by the
balance between the gravitational and electromagnetic forces. A cusp may
develop even in Newtonian tori due to the charge distribution.
