Abstract:
The present invention relates to a reversible permeability measuring device for measuring magnetic characteristics and magnetic flux change in a specimen, as one of a plurality of non-destructive methods for evaluating mechanical properties. The reversible permeability measuring device of the present invention directly measures a magnetic field change induced at the surface of the specimen through the use of a magnetic potentiometer and a flux meter, thereby accurately evaluating the deterioration of materials.
