What is the eddy current inspection and how does it work?
In an eddy current probe, an alternating current flows through a wire coil and generates an oscillating magnetic field. The eddy current instrument plots changes in the impedance amplitude and phase angle, which can be used by a trained operator to identify changes in the test piece.
