This method employs an asymmetrical \"M-shaped\" magnetizer, using pole shoes of different thicknesses to achieve layered magnetization. By analyzing the differences in MPPT signals to classify defects effectively. A magnetic circuit model and a finite element simulation model with varying pole-shoe thicknesses were established, revealing that varying the pole-shoe thickness can change the magnetization level. An experimental platform was constructed to validate the simulation results. Theoretical and experimental analyses demonstrate that the method is user-friendly, highly efficient in detection, and capable of classifying internal and external defects of various sizes on ferromagnetic components with a thickness of 20 mm. Notably, the method shows resilience against variations in defect size and component thickness. Selecting the optimal combination of pole shoe thicknesses can help improve classification accuracy.
