Kinetic inductance charges and its role in electrodynamics

The material medium is differed from vacuum in terms of the fact that it consists of the connected or free charges. Pour on charges they begin to move during the imposition on this medium of electrical. But any charge has mechanical mass, and the presence of this mass affects the dynamics of its motion. From an electrodynamic point of view the calculation of the mass of charge in such processes can be taken into account by the way of the introduction of this concept as the kinetic inductance of charge. This parameter has the same important significance as the dielectric and magnetic constant of material media.
