    Abstract:
    Charged fluids circling in strong central gravitational and ambinet magnetic fields, characteristic for compact objects backgrounds, can embody interesting configurations. In contrast to the widely considered neutral fluid structures imitating thick equatorial accretion discs with negligible loss of mass, when the fluid is properly charged, we can find it forming unique toroidal structures `levitating‘ above the equatorial plane and also those hovering near the symmetry axis. Along with analytical topological studies of these structures, we can also present an survey of their basic physical characteristics, such as pressure, density and temperature profiles.
