概要

There are various inspection methods using Magnetic Flux Leakage Testing. In this paper, we attem pt to apply Thin-Film Flux Gate magnetic sensor to measure weak leakage flux density induced by s urface or back surface defects like cracks or notches. And it is shown that the measured magnetic flux density near the specimen surface indicates the pattern reflecting the shape of the defects.
