Measurement of propagation velocity of bound electromagnetic fields in near zone

We start with the general approach based on conventional solutions to Maxwell's equations and show that in the near zone of macroscopic electromagnetic sources the electromotive force produced in receiving loop antenna is intimately linked to the fundamental structure as well as to causal properties of the classical electromagnetic field as a superposition of bound and radiation components. As a consequence, we propose and implement a direct experimental procedure for the correct identification of retarded positions of bound field contributions on the oscilloscope time scale as a function of a distance from the emitting loop antenna. It provides unambiguous empirical information on causal characteristics of bound electromagnetic fields. According to the observation of no retardation inside the near zone of the emitting loop antenna, the experimental evidence for nonlocal properties of bound electromagnetic fields is reported

Force law in material media and quantum phases

We show that the known expressions for the force on a point-like dipole are incompatible with the relativistic transformation of force, and in this respect we apply the Lagrangian approach to the derivation of the correct equation for force on a small electric/magnetic dipole. The obtained expression for the generalized momentum of a moving dipole predicts two novel quantum effects with non-topological and non-dynamic phases, when an electric dipole is moving in an electric field, and when a magnetic dipole is moving in a magnetic field, respectively
