摘要
本文由标量磁位计算圆柱形点缺陷的漏磁场 ,然后计算穿过式线圈及旋转式线圈探测点缺陷的漏磁场产生的感应电动势 。
Magnetic flux leakage of cylinder point flaw was computed by using scalar quantity magnetic potential method.The potential induced by magnetic flux leakage of point flaw detected b through loop or revolving loop was calculated.The conclusion can be obtained by analyzing character of these testing signals.
