Abstract
Mathematical expressions are derived for the changes in resistance and inductance of a single turn of thin wire, due to the presence of a conducting sheet of finite thickness with its surfaces parallel to the plane of the coil Computed results from these expressions are presented, for the case of a non-ferromagnetic sheet, illustrating the effects of variations in sheet thickness and conductivity, the separation of coil and sheet and in frequency of the coil current. These results are relevant to the design and operation of instruments for lead cable-sheath testing.Keywords
