Stationary configuration of a rotating electrically charged ideal fluid with self-gravitation is considered within the framework of general relativity. Barotropic equation of state of the liquid is p = wε (w = const). A combination of a longitudinal magnetic field and a vortex gravitational field is considered. The boundaries of the interval of the barotropic coefficient w in which the material system under study can exist are found. It has been shown that for w > 0, the formation of wormholes is possible. Corresponding solutions describing the space-time wormhole geometry are found.
