Ferromagnetic　components　are　susceptible　to　various　defects　after　prolonged　service.　The　defects　generated　in　these　components　are　diverse　and　exhibit　irregular　orientation,　which　may　impede　comprehensive　defect　examination　using　a　single　magnetic　testing　method.　This　paper　proposes　a　novel　magnetic　measurement　sensor　that　integrates　the　principles　of　magnetic　flux　leakage　(MFL)　and　magnetic　field　disturbance　(MFD).　The　combined　theory　is　analyzed　and　validated　through　the　utilization　of　finite　element　method　(FEM)　simulations　as　well　as　experimental　investigations.　By　comparing　simulation　results　with　experimental　data,　the　composite　nature　of　the　signal　acquired　beneath　a　magnetic　bridge　is　convincingly　demonstrated.　In　comparison　to　conventional　MFL　and　MFD　methods,　this　innovative　sensor　exhibits　superior　defect　detection　performance　for　varying　angles　and　widths,　while　also　addressing　some　inherent　limitations　associated　with　MFL　and　MFD　principles.
