Abstract
This paper suggests a possible explanation to the geometry-dependence of core loss by solving Maxwell's equations for the flux distribution inside a magnetic conductor carrying eddy currents. The solution reveals a displacement of flux towards the edges of the magnetic sheet. Core loss with and without the displacement effect are compared for the tooth of a highly excited and high-frequency electric machine. A significant difference from standard calculation methods is obtained.
