Abstract

From the differences in the complex impedance between a circular solenoid coil surrounding a coaxial with a cylindrical conductor and a similar coil without the conductor, a method for measuring resistivity and permeability of the conductor is proposed. The resistivity of copper measured by this method has correlated well with the values measured by the DC four-probe method. Furthermore, the experiment with a high-T _c superconductor indicates that the resistivity and permeability of the conductor can be measured with remarkable accuracy
