摘要
Using nonlinear electrodynamics coupled to teleparallel theory of gravity,regular charged spherically symmetric solutions are obtained.The nonlinear theory is reduced to the Maxwell one in the weak limit and the solutions correspond to charged spacetimes.One of the obtained solutions contains an arbitrary function which we call general solution since we can generate from it the other solutions.The metric associated with these spacetimes is the same,i.e.,regular charged static spherically symmetric black hole.In calculating the energy content of the general solution using the gravitational energy-momentum within the framework of the teleparallel geometry,we find that the resulting form depends on the arbitrary function.Using the regularized expression of the gravitational energy-momentum we obtain the value of energy.
