Abstract
Eddy current testing is a nondestructive testing method based on electromagnetic induction principle. The metal conductor is placed in an alternating magnetic field, and the eddy current will be induced. Hughes used the induced current method to detect the different metals and alloys, explained the feasibility of using the eddy current to detect defects of the conductive material in 1879. However, after that for a long period of time, the eddy current testing technology has developed slowly because there were no effective methods to suppress the interference factors.
