ABSTRACT:
A probe comprises a magnet and a Hall element which are provided in a magnetically impermeable case. The Hall element is disposed at the midportion between the two poles of the magnet in parallel with the lines of magnetic force. The presence of a carburized portion in the member to be inspected and the depth of carburization are detected by passing d.c. current across the Hall element and detecting the Hall effect electromotive force produced between the two ends of the element which are opposed in a direction perpendicular to the direction of flow of the current.
