The Magnetic Current Component in the Conductivity Tensor

The theory of electromagnetic in nature new component of electrical current is suggested. In classical physics approximations for the cases of the free electron plasmas in semi-conductive media, the atom or molecular electrons of liquids and amorphous or polycrystalline solid states medias, tensors of conductivity are calculated. It is shown that the resolution of the additional members of the tensors of conductivity in degrees of the spatial dispersion parameter the series begins minus two degree this parameter, not the only conventional null degree in beginning takes place. The joined optical spatial and time dispersion effects are to be needed for the experimental observation this non-conventional component of the electrical current. Some discussion of this problem is given. In particular, the two-wave propagation effect predicted is discussed.

Electrostatic Field of Charged Infinite Metallic Plane Contacting with Metallic Sphere

The problem concerning the form of the electrostatic field potential of the infinite charged metallic plane contacting with the metallic sphere is solved. The distributions of the surface charge densities both on the plane and the sphere and also the force acting on the sphere that causing to tear away from the plane are found. The expressions found for the charge of the sphere and the force of tear from the plane permits estimate the frequency of the shuttle motion of the nanoparticles and the charge transfer between metallic electrodes and also use them for the measurement of their sizes and to make use of their separation in progress.
