Approaches to permanent magnet circuit design

Discusses some of the more fruitful approaches to the use of high coercivity/high remanence magnet materials in magnetic circuit design and how the application of comparatively few and simple techniques can result in a large number of useful devices. The approaches discussed are the estimation of permeances, magnetic cladding, equivalent pole densities and current sheets, analytic application of Maxwell´s equations, the magnetic moment rotation theorem and magnetic mirrors. Some novel devices resulting from these applications are cited
