摘要：

Alternating magnetic flux leakage testing is one of the surface inspection method for iron and steel in iron works. This method consists of detecting leakage nux from cracks on ferromagnetic material magnetized by alternating magnetic flux by an exciting coil. But an evaluation method for this testing is not always established Therefore we propose an approximate numerical analysis for alternating magnetic Our leakage testing. We clarify the phenomenon of alternating magnetic flux leakage testing using the approximate numerical analysis method.
