Soft Magnets: Applications and Loss Mechanisms

This lecture covers the definition of soft magnets, magnetization reversal via domain wall motion in weak fields, applications of soft magnets to exploit magnetic flux, prototypical soft magnets like single-crystal iron, overview of soft magnet applications in transformers, comparison of transformer cores, coercive field and magnetization of different soft magnetic materials, and losses in AC applications of soft magnets focusing on hysteresis and eddy current losses.
