The analytical method is developed to calculate the three-dimensional quasi-stationary electromagnetic field generated by arbitrary spatial current contour near the conducting body 1 / 3 2018 N1 st1 with plane surface. By the use of displacement currents in dielectric region under quasi-stationary approximation, in addition to the results presented earlier, the solution for the scalar potential and electric intensity in entire dielectric half-space is found. Owing to the established fact of vertical zero components of the electric intensity and current density in conducting half-space, the electric field of surface charge compensates completely the vertical component of induced electric intensity of the initial current system. As an example, the electric intensity and surface electric charge density are calculated for the current contour configuration typical for technological systems. References 13, figures 3.

On the basis of the analytical decision of problem on a field of radiating harmonious current dipole the analytical calculation method of quasi-stationary three-dimensional electromagnetic field created by arbitrary spatial current contour, located near conducting body with a flat surface is developed. The analytical decision taking into account closed current contour is found for vector potential, induction of magnetic field and intensity of electric field in dielectric and conducting media without limitations on contours geometry, media properties and current frequency It is established, that the current density in the conducting medium has no component directed perpendicularly to flat surface of body for any initial current system and for any

The mathematical model has been developed to determine of the induced pulsed density current in the conductive sheet and the current parameters of the inductor contour for non-contact electric pulse processing of materials. Based on the calculated data, the prospects of using inductors in the form of current contours for influencing the weld due to the "electroplasticity" effect in the local area are shown.
