Abstract

We extend a procedure to determine the optimal magnet design in the framework of Lorentz force eddy current testing. We consider classical cylinders and Halbach magnet systems for specimens made by metal injection molding. Evaluating as objective function the absolute defect response signal of the Lorentz force measurements using finite element method leads to an optimal and specific magnet design for each defect scenario. The proposed Halbach magnet enables defect responses up to four times higher outperforming cylinder.
