This paper presents a quantitative evaluation index efficiency of eddy current and defect interaction to evaluate the eddy current distribution induced by different planar eddy current probe. Efficiency’s definition and its calculation method are presented. Eddy current induced by three different exciting coils interacting with defects having different lengths and different orientation angles is analyzed by the proposed method. Finally, the paper highlights strengths and weaknesses of the studied current probe inducers and an improving method is proposed.
