The effect of plastic strain on magnetic behaviour was studied earlier by many authors. These studies mainly focused on plastic straining obtained by tensile testing and on magnetic measurement along the tensile axis. We present in this paper some new results showing the influence of a plastic shear strain obtained thanks to a torsion test on the magnetic behaviour of a pure iron. These results highlight the dominant role of the cumulative plastic strain on the magnetic behaviour.
