We present a method for the analysis of ferromagnetic shields under low-frequency excitation conditions and demonstrate its validity. The source types are arbitrarily oriented current loops or multiconductor lines. We account for hysteresis by means of the Jiles–Atherton model and solve the relevant equations in the time domain by adopting a finite-element time-domain procedure.

Abstract
We present a method for the analysis of ferromagnetic shields under low-frequency excitation conditions and demonstrate its validity. The source types are arbitrarily oriented current loops or multiconductor lines. We account for hysteresis by means of the Jiles–Atherton model and solve the relevant equations in the time domain by adopting a finite-element time-domain procedure.File allegati a questo prodotto
