Abstract :
In order to reach a significant comparison between measured and computed curves, we carry out a VSM hysteresis measurement and a simulation for the experimental device which measures the hysteresis loops. The aim of our paper is to present the details of such a simulation, using 2D-finite element analysis combined with a model based on a gaussian assembly of uniaxial anisotropy particles. The intrinsic hysteresis characteristics are computed and compared to the measured ones.
