Half-order modelling of ferromagnetic sheet

Abstract

This paper presents a half-order modelling approach applied to a saturated ferromagnetic sheet. Several analytical models are then developed and compared for one-dimensional formulation. In order to identify parameters and validate such models, the saturated ferromagnetic sheet has been simulated using Flux® finite element simulation software. The proposed model has been finally validated by performing the impedance measurements on the real ferromagnetic saturated sheet, using Agilent HP 4294A impedance meter. This model takes into account diffusion of the magnetic field in conductive materials and magnetic saturation.
