This article is a continuation of the previous author's article on the same problem [1], Here choice of metrics discusses in detail, so as another possible metrics, like generalization of the Schwarzschild metric of massive body due to radiation of electromagnetic wave. A problem of lowering the initially spherical symmetry to axial one in solution’s level for Einstein−Maxwell (or Maxwell) equations due to fixation of z-axis of coordinate system and its recovery with the help of zero-modes is discussed.
