with coordinate system replacement. The weight of the product of two tensors equals the summarized weight of tensors of each factor and convolution of each pair of indexes, con- sisting of the identical upper and lower indexes, does not change the weight of tensor; all pseudo-tensors considered in the paper have weight ± 1; in particular, a magnetic charge is a pseudo-scalar, see below, and, hence, we are not far from the fore-quoted Weinberg statement. 

The left-hand part of equation (4a) represents by itself a tensor of the third rank, which is antisymmetric in all indexes. Having lowered indexes of this tensor, multiplied by e mlik and performed convolution with respect to three pairs of identical indexes, we obtain equation

The relation between components of pseudo-tensor F ⋆ $_{A$_{e}$}$, which is dual to F$_{A}$$_{e}$ , and compo- nents of (three-dimensional) vectors of electrical field E and magnetic field H is described as

i.e. in pseudo-tensor F ⋆ $_{A$_{e}$}$, as compared to tensor F$_{A}$$_{e}$ , components of (three-dimensional) vectors of the electrical and magnetic fields change places. So, it would appear reason- able, that the electromagnetic field generated by the current density of magnetic charges { µ$_{b}$ } – j$_{µ}$ could be described using the antisymmetric four-dimensional pseudo-tensor of the second rank, F$_{B}$$_{µ}$ , which is structurally similar to pseudo-tensor F ⋆ A$_{e}$ and described via four-dimensional pseudovector-potential B i µ ≡ ( ψ$_{µ}$, B$_{µ}$ ) in the following way:

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