Based on the wave equation for spin-one particles (vectons) proposed earlier by the author, we select an interaction operator and then in the limit go to field variables and the Maxwell equations of classical electrodynamics. Additional terms arising in this case are interpreted as magnetic charges and currents. We discuss the consequences. We conclude that it is possible to find magnetic charges in matter and present some characteristics of such materials. We logically derive free magnetic charges and their currents. We construct an electrodynamics taking into account material media.
