Understanding how stress changes magnetism in iron and other metals. This exploration explains how applying and removing load alters magnetic behavior, sometimes in subtle ways and other times with striking changes in how the material responds to magnetic fields. The discussion centers on experiments and observed effects that reveal hysteresis in both magnetic susceptibility and related properties.
Drawing on classic studies, the text shows how the curve of magnetisation can shift depending on prior stress, even when the metal returns to a non-magnetic state. It highlights residual effects, the impact of vibration, and how small molecular changes can lag behind applied forces. The material is presented with clear descriptions of the setups and outcomes, offering a concrete view of the physics behind magnetism in iron and similar metals.
