Integral-equation approach for the Bean critical-state model in demagnetizing and nonuniform-field geometries

Abstract

This paper describes an integral-equation approach to solving for the flux-front profile in the critical-state model. Both nonuniform external fields and demagnetizing geometries can be accommodated as long as cylindrical symmetry is preserved. The solution for a sphere in a uniform external field is presented and compared with those of other calculation techniques.
