• A magnetic probe containing a Hall sensor and pickup coil was developed, and its accuracy was confirmed by comparison with standard ring sample results under zero stress. The magnetic minor hysteresis loops of a low-carbon steel plate sample were measured by using this probe under uniaxial tensile stresses. It was found that both the coercivity Hc and hysteresis loss W_F can be measured accurately by means of a magnetic probe. In the perfectly elastic region, from 0 to 90 MPa, Hc and W_F decrease with increasing external stresses due to domain re-orientation, and they start to increase a little in the micro-plastic range. In the plastic stage, Hc and W_F increase almost linearly with external stresses as a result of dislocation pinning effects. This clear relationship between magnetic properties and external stresses is also valid for NDE applications.
