A model of electro-magneto-thermo-mechanics for electroconducting polarized nonferromagnetic medium is proposed which takes into account the local mass displacement in addition to the local electric charge displacement. The corresponding key set of equations is written. Using the isothermal approximation, the model is applied to describe the interface inhomogeneity of a stressed state, the polarization and coupled electric charge in thin dielectric films. An anomalous dependence of the electric capacity on the thickness of a thin dielectric film, observed experimentally by Mead, is also studied and is shown to be well captured by the present approach.
