Abstract :
A model has been proposed to evaluate magnetodynamics properties based on a variational principle. The proposed method consists of two steps; (1) deriving magnetodynamic properties from the power functional through a variational principle and, (2) performing a spatial averaging procedure to discriminate the various scales by the dynamic magnetization process.
