概要
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 permalloy under tensile loading exhibited that By increased with increasing stress.
