Tensor hysteresis loops with minor loops are measured for a 25.4 mm line pipe steel cube while compressive stresses are applied in the directions orthogonal to the applied field. The reversible (RDMS) and irreversible (IDMS) differential magnetic susceptibilities for each element are derived and the effects of compressive stress are studied. It is found that for diagonal elements, applied compressive stress does not effect the RDMS elements, except for the effects of residual stress, and the IDMS is less than its RDMS, respectively. Reversible magnetization rotation dominates the magnetization process as saturation is approached in both diagonal elements and off-diagonal elements.
