摘要：

In order to estimate non-destructively a defect shape on the I eva se side of a thick stainless steel plate, we improved a rotational magnetic flux sensor with a three-axis search coil. By using specimens with a defect, we investigated the relationship between the defect shape and output signals of the three-axis search coil. From results of our experiments, it can clearly distinguish several types of the defect shape existing on the I eva se side of sensing surface. In this papa, we present the construction of the rotational magnetic flux sensor with the three-axis search coil, results of numerical analysis and experimental results.
