Due to the strongly nonlinear behavior of ferromagnetic yokes, the numerical analysis of fast-ramping magnets is highly cumbersome and, therefore, in practice overly simplified by means of anhysteretic material descriptions and a posteriori loss formulae. This paper establishes the use of a dynamic ferromagnetic model combining a preconditioned energy-based hysteresis description and a thin-sheet eddy-current model in time-domain. The model was successfully employed in the analysis of a normal-conducting bending magnet in order to precisely calculate losses and fields.
