  • Patent number: 9146214
    Abstract: A magnetic flux leakage inspection method generates a magnetic flux parallel to a surface of an inspected object, and detects a magnetic flux that leaks from the surface of the inspected object with a magnetic sensor. The method includes exciting coils that generate an alternating magnetic field having a variable frequency, an exciting coil power source, a magnetic sensor, a lock-in detector, and a signal analyzer that analyzes changes of a signal intensity and a phase of the output of the magnetic sensor with output signals of the lock-in detector. The method obtains cosine or sine as a trigonometric function of a phase obtained by adding to the phase at each measurement point of multipoint measurement, an adjustment phase common to all the measurement points, and displays an analytical value obtained by multiplying the signal intensity and the sine or cosine at each measurement point with any adjustment phase.
