The Characteristics and Principle of Eddy Current Inspection
Eddy current inspection is an alternating magnetic field generated by an alternating current that acts on the conductive material to be tested, and induces an eddy current. If there is a defect in the material, it interferes with the generated eddy currents, i.e. forms an interference signal. The status of the defect can be known by detecting the interference signal with the eddy current flaw detector.
