Abstract

To more accurately estimate the resistivity and permeability of a cylindrical conductor sample, a formula for obtaining the difference in the complex impedance between a circular multilayer solenoid coil having a conductor and a similar coil without a conductor is derived. In comparison with the conventional method using a single-layer solenoid coil, it is shown by experiment that a multilayer solenoid coil is extremely effective with regard to a short conductor sample because a larger difference in the complex impedance is obtained without increasing the width of the solenoid coil
