{ g$_{b}$ } – j$_{g}$ could be described using the antisymmetric four-dimensional pseudo-tensor of the second rank, F$_{B}$$_{g}$ , which is structurally similar to pseudo-tensor F ⋆ A$_{e}$ and described via four-dimensional pseudovector-potential B i g def = ( ψ$_{g}$, B$_{g}$ ) in the following way:

Then, instead of equations (4)-(6), (11), to describe the electromagnetic field (in vac- uum), generated by the current density of magnetic charges j$_{g}$ , one could use the following 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$_{i}$ ,
