Energy in Oriented Lamination

Abstract

The experiments prove that the rolling technology and the cutting procedure have effect on the energy stored in magnetic sheets. The variation of the energy with the angle between the homogeneous external magnetic field and the easy axis of the material is examined with parallel and cross stacking of the sheets. The magnetic field generated by the external field is determined by global variation method. The interaction between the external and the internal fields is taken into account as well. The boundary conditions are fulfilled on the basis of R-function method.
