Abstract

Lorentz force eddy current testing is a recently developed new technique in the framework of motion induced eddy current testing (MECT). In contrast to existing MECT systems, a new portable system is investigated, where the magnet is moving and the electrically conductive specimen is at rest. In this study new solution approaches for possible patterns of motion are elaborated. Finally, the translational and rotational motion of an axial magnetized permanent magnet above a specimen with a defect are discussed.
