ABSTRACT:
The induced magnetic field detecting apparatus of the present invention is configured so as to irradiate laser light onto an inspection target from the same side as the side on which a pickup coil for magnetic field detection is disposed and be able to perform irradiation of the laser light and detection of a magnetic field induced by the irradiation of the laser light on the same side relative to the inspection target. Furthermore, the induction magnetic field detection apparatus of the present invention adopts a configuration in which laser light is irradiated onto the inspection target through the inside of the loop-shaped pickup coil set up inside the container. This configuration exerts an effect of being able to detect a feeble magnetic field with higher accuracy.
