## Abstract 

The paper offers the full action for an electromagnetic field with electrical and magnetic charges; it is marked, that it is hard to give an accurate formulation of Feynman laws for the calculation of the interaction cross-sections for electrically and magnetically charged particles on the base of offerd action within relativistic quantum field theory, simple partial case of a constant electromagnetic field is considered.
