Strain annealing, as a recent development in magnetic material post processing, is able to produce a continuum of relative permeabilities. Certain alloys can range down to 30% of nominal while maintaining mechanical stability. This achievement represents a significant paradigm shift in the design of electro-magnetic devices. This new process has the ability to graduate the permeability for evenly distributed core flux, eliminate the need for air gaps with precision tuning, and flux guides with localized variations. All of these will eliminate the need for mechanical cuts in the core material. The final paper will explore the impact of these design changes. Along with verifying efficacy, it will focus on the flux behavior at the interfaces of permeability change. Specifically, the paper will answer questions regarding the degree to which flux deflections at the interface behave like fringing through an inductor and transformer design example.
