Knowhow of applying impulse electrical exploration, using transverse magnetic (TM) polarization of electromagnetic field or of non-stationary field of electric type has been considered. Such polarization is obtained in case of excitation by vertical electric dipole or, from the day surface, by circular electric dipole.
