Abstract
Equations, describing the distribution of electromagnetic field induced by currents of (1.1) type flowing in the circular coil, including symmetrically infinitely long metal cylinder (fig.1), are presented in the paper. In spite of simply physical configuration, they are very complicated. Main research goals set by authors are presented below: a/ general analyze of electromagnetic field in the considered configuration, b/ examination of electromagnetic waves in the distant zone with respect to possible interferences, c/ examination of influence of Maxwell displacement currents on distribution of field in the environment of metal wall (circular cylinder) of curved surface. It is obvious, that in the case of surface, which is not curved, influence of Maxwell displacement currents on distribution of field in the near zone is negligible. Influence on the distribution of electrical field is essential and cannot be omitted even during the approximation [1]. However, in the case of cylindrical wall, Maxwell currents may influence significantly even on the distribution of magnetic field (in the case of exciting currents flowing in the linear conductors, which are parallel to the axis of cylinder) [2].
