Exact solutions of the Einstein–Maxwell equations in GTR for centrosymmetric dust and a free electromagnetic field are applied to a description of pinch plasmoids formed in experiments on the collapse of a charge-neutralized high-voltage discharge in a medium in which superhigh energy densities are reached, where an account of the curvature of spacetime becomes important. The given solutions are also used to estimate the parameters of cosmological objects – maximons, whose electric charge is equal to the “gravitational charge.” These objects are identified with the throat – the extremal static hypersurface of the inner space of the plasmoid and maximon observed from the Reissner–Nordström vacuum.
