Short summary
Lorentz force eddy current testing (LET) is a motion-induced eddy current testing method in the framework of nondestructive testing. In this study, we address the question of how this method is classified in comparison with a commercial eddy current testing (ECT) device. Therefore, measurements using both methods are performed and evaluated. Based on the measurement results, the corresponding defect detection limits are determined and discussed.
