Abstract: This paper explored some influencing factors of AC electromagnetic field detection technology. By using simulation, the influence of factors such as conductivity, magnetic permeability, defect length, defect depth, lift-off height, and defect burial depth on the results of AC electromagnetic field testing was studied, and formula fitting was perfomed. The reliability of simulation results and fitting formulas through test blocks were verified, providing reference for setting AC electromagnetic field detection parameters.
