Maxwell equations for the electromagnetic fields coupled with the spin-polarized electron gas have been developed from the variation of the functional path integral. Additional terms in Maxwell equations depend on magnitude and type of the spin-orbit coupling of a two-dimensional electron gas. It was shown that additional terms appear in Ampere law in the presence of spin-polarized electron gas with spin-orbit coupling. This terms act like an effective electrical current density and depend on the magnitude and type of spinorbit coupling and on the value of spin density.
