| Abstract: | The magnetic flux leakage of cylindrical point flaw was calculated by scalar magnetic potential method. The potential induced by the magnetic flux leakage of point flaw detected by passing through coil or revolving coil was calculated. Conclusions were obtained by analyzing the characters of the testing signals. |
