Possible Future Trends and Research Challenges related to 1 & 2 D Magnetic Properties of Soft Magnetic Materials

One and two dimensional magnetisation studies of bulk soft magnetic materials have been researched and characterised over the past 100 years. Initially, focus was on dc rotational hysteresis and this has evolved to studies of losses permeability, and magnetostriction, mainly of electrical steels, under controlled complex magnetisation of the type known to locally occur in rotating machine and transformer cores. This paper briefly summarises present knowledge and then some new and unsolved problems of interest or potential industrial importance are reviewed.
