Magnetic flux leakage measurements were performed by using a fluxgate sensor. For an artificial defect of 0.3mm width of SS400 steel, changes in p erpendicular magnetic flux leakage B, could be measured at a lift off height of 5mm, and changes in longitudinal magnetic flux leakage B, could be measured at a lift off height of 10mm. For artificial surface defects, magnetic flux density distribution of By was well correlated to the shape o f the defects. In-situ magnetic flux density measurement By for permal...

Using Hall and ECT sensors, a non-destructive damage evaluation was performed for the specimen of rail eel with simulated white damage layers. Two types of specimens were used, one with a simulate d white amage layer of 1mm depth and the other that of 100um. First using Hall sensor, distributio n of magnetic ux around the white damage layers was measured by means of magnetic flux leakage tec hnique. Both agnetic flux leakages of B, and B, revealed the presence of the white damage layers. Also from the ag...
