Lorentz force eddy current testing (LET) is a novel nondestructive testing technique which can be applied preferably to the identification of internal defects in nonmagnetic moving conductors. The paper describes the comparison with established eddy current testing technique. The investigation of the performance of LET has been performed providing a qualified comparison (similar testing conditions) with the classical eddy current testing (ECT). Additionally, numerical simulations have been done. The results are compared with measurements to test the feasibility of defect identification.
