Abstract
With appling to geoelectric we consider the problem of electromagnetic excitation of layered (horizontal-<br>and cylindrical-layered) mediums by external "magnetic current". In particular, excitation<br>by an axial magnetic current (toroidal coil with current) which is the inductive analogue of vertical<br>electrical dipole. Obtained solutions are represented by integrals which are su ciently simple for<br>algorithmization.
