In this paper,the ansys simulation analysis on aluminum alloy plate,copper plate,and stainless steel plate under the different frequencies with the same artificial defects were carried out.Through the analysis of the magnetic field lines in the electromagnetic field distribution,the test gives the real and the imaginary part of the current,and the corresponding impedance map is obtained.The simulation result points out that the impedance of the coil is changed due to the resistivity,frequency and defects.The conclusion is valuable for practical testing.
