Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of problems because of its large flexibility which allows to deal with complex probe and part configurations. In this context, the benchmark problems TEAM Workshop 15-1 and JSAEM 2–5 have been considered to validate a COMSOL-Multiphysics resolution using a 3D electromagnetic formulation with Whitney edge elements. This study shows a good agreement between the numerical results obtained by COMSOL Multiphysics and the experimental ones.
