On the Problem of Ambiguity of Electromagnetic Potential (1307.0460v1)

Abstract: In the self-sufficient potential formalism, treating all electromagnetic phenomena as natural or forced oscillations of some distributed electromagnetic oscillating system (Minkowski space-time), the electromagnetic potential must be considered as some relative measure describing deviation of the system from its "undisturbed" state (when both natural and forced oscillations are absent). Therefore, there is no ambiguity in the gauge of one: all components of the potential four-vector are asymptotically verging towards zero while the distance from all free charges and currents enlarges. Such interpretation turns the electromagnetic potential into a physically real value.
