The effective impedance of a coil in front of a metal plate varies with the applied frequency. From a physical mathematical standpoint, analysis of the characteristics was already completed by deciding the Green's function. But the effect of the method generally can not be adaptable to the experimental phenomenon, for the reason that the function contains some integrals with an infinite integration of Bessel functions, and then can not be integrable without a larger digital computer. The authors integrated the function by approximation under the some assumptions. This report was described about the approximated integration when a coil faced a thick ferromagnetic metal plate and the calculations of the specific permiability by the experimental measurements.
