Abstract

The effect of applied external stress on the magnetic properties of ferromagnetic
materials has been recognised as one of the most important ferromagnetic
phenomena for over a century. Research into the field has been driven by investigations
of non-destructive testing, degaussing, and maritime applications.
A comprehensive investigation of the magnetomechanical behaviour of mild
steel under static biaxial stresses was undertaken with the intention of adapting
and improving techniques of obtaining magnetic and strain data, producing
accurate data for analysis, and developing insights into a tentative alternative
theory of stress and magnetism.
A method of obtaining Initial Magnetisation Curves is presented which equates
them with Normal Magnetisation Curves. A conceptual mechanism by which applied
stress and magnetism interact is introduced in order to explain coincident
points and kinks on hysteresis loops obtained at different, static biaxial stresses.
Finally the set of biaxial strain and magnetisation data is presented for a mild
steel cruciform specimen.
