Abstract
A method to simultaneously measure the resistivity and the permeability of a sample conductor from the difference in the complex impedance obtained by measuring the vectors of two identical circular solenoid coils, one surrounding and coaxial with the sample conductor moving at a constant speed and the other without the sample conductor is studied.The sample conductor in the study moved at a constant speed but when the measuring frequency is high enough, the effect of the speed on the complex impedance becomes insignificant.In this paper, the lowest possible measuring frequency which keeps, within 1%, the effect of the speed on the difference in the impedance between a static and a moving sample s shown. The resistivity and initial permeability of an iron sample were measured under such condition. These values were compared with values obtained by conventional methods. The difference in the values for the resistivity of an iron sample was within 8.3%, and for the initial permeability within 3%.
