Effective gravitational mass of the Ay\'on-Beato and Garc\'a metric
Abstract
In this paper, we calculate the effective gravitational mass of Ay\'on-Beato and Garc\'a regular (non-singular) static spherically symmetric asymptotically Minkowskian metric that is a solution to Einstein's equations coupled with a nonlinear electromagnetic field. The effective gravitational mass is negative, zero, or positive that depends on the ratio of magnitude of electric charge to the ADM mass and the ratio of the radial distance to the ADM mass. As expected, at large value of radial distance, our result gives effective gravitational mass of the Reissner-Nordstr\"om metric.
