Relation between magnetic flux leakage (MFL) and magnetization of a ferro-medium circular cylinder is set up. We can predict magnetization of material according to the MFL on surface of the circular cylinder.展开更多

文摘Based on the Ampere molecular current hypothesis and the Biot-Savart law, a magnetic model on the metal magnetic memory (MMM) testing of a specimen is proposed. Relation between magnetic flux leakage (MFL) and magnetization of a ferro-medium circular cylinder is set up. We can predict magnetization of material according to the MFL on surface of the circular cylinder.
