ABSTRACT In the inductive method of prospecting, information on conductivity and size of conducting ore‐bodies located in non‐conducting host rocks, can be conveniently obtained by studying amplitude‐frequency relation or amplitude‐phase relation of their response with the help of suitable Master‐curves. Experiments carried out in the laboratory on the scale‐model method show these Master‐curves to be different depending on the type of primary excitation and the shape of conductor. Cases of sphere, plate and disc in uniform field, field of line source and dipole field have been studied with an Amplitude‐Phase Meter specially constructed in the laboratory for this purpose.
