Abstract: In this article, this measurement result was found that the fluctuation amplitude of the coil¡¯s inherent inductance L gradually reduces with increasing of frequancecy while the fluctuation amplitude of the coil¡¯s inherent resistance R gradually increases with the increasing of frequancecy. According to the basic principle of eddy current testing, some experiments in this paper proved that the equivalent resistance R and the equivalent impedance Z of the eddy current testing equivalent circuit is unstable in repeated measurements, but the equivalent inductance L has a good stability and can be used to measure the height of copper cylinder at an appropriate frequancecy after doing a calibration between the equivalent inductance L and the height of copper cylinder. Besides, the abnormal measurement result of the equivalent inductance L was illustrated by the finite element electromagnetic field simulation when the copper cylinder is too high.
