... using this technique. Magnetoacoustic Emission Magnetoacoustic emission (MAE) is caused by microscopic changes in strain due to magnetostriction when the discontinuous irreversible domain wall motion of the non-180┬░ domain wall occurs ( Ref 40 ). It arises when ferromagnetic steels are subjected...
