equations: To obtain a closed equation system, describing the electromagnetic field together with electrical and magnetic charges, equations (4b) and (15b) must be complemented with mo- tion equations for electrical charges and magnetic charges In equation (19), m$_{a}$ is the a -th electrical charge’s mass, ds = √$_{dx}$ $^{i}$dx$_{i}$ , is the without size four-dimensional velocity of the a -th electrical charge. The same notations are used in equation (20). In the right-hand parts of equations (19), (20) in parentheses the electrical and magnetic fields, generated by electrical and magnetic charges, are summarized, according to the superposition law. Equations (19), (20), (4b), (15b) can be obtained, basing on the requirement of for variation of the full action, 6 m$_{a}$ c du i a ds = e$_{a}$ c ( F ik A$_{e}$ + F ⋆ ik B$_{µ}$ ) u$_{a k}$ (19) m$_{b}$ c du i b ds = µ$_{b}$ c ( F ⋆ ik A$_{e}$ + F ik B$_{µ}$ ) u$_{b k}$.
