Abstract:
The present invention quickly carries out quantitative evaluation of a defect of a magnetic member. An inspection probe ( 100 ), which includes: a third magnet ( 4 ) polarized in a direction intersecting a counter surface facing a magnetic member; a Hall element ( 11 ) that detects a density of a magnetic flux passing through the third magnet ( 4 ) and the magnetic member, is used to apply, to an output signal from the Hall element ( 11 ), an evaluation algorithm which is selected according to whether a defective surface is a front surface or a back surface.

Claim (Index 1):
A method of measuring a defect of a magnetic member, comprising the steps of:\n (A) measuring an output from a magnetic sensor with use of an inspection probe including a magnet and the magnetic sensor which is provided on a magnetic circuit formed by the magnet and the magnetic member and which detects a density of a magnetic flux flowing through the magnetic circuit; (B) judging whether the defect is (i) a front surface defect occurring to a front surface of the magnetic member, which front surface is a counter surface facing the inspection probe or (ii) a back surface defect occurring to a back surface of the magnetic member, which back surface is opposite the counter surface; and (C) quantitatively evaluating the defect of the magnetic member by applying, to an output signal from the magnetic sensor, an evaluation algorithm which is selected from evaluation algorithms set in advance for the respective ones of the front surface defect and the back surface defect and which corresponds to a result of the judging in the step (B).
