Abstract
The magnetic behaviours of grain-oriented, non-oriented and rapidly qu enched iron-silicon alloys are modeled according two analytical models . The first one (Wong's model) describes the variations of the inducti on B as a fraction of (H +/- H(c)). The second (Gonda's model) defines the B behaviour as an exponential function of (H +/- H(c)). The fit c haracterized by the difference between experimental and analytical hys teresis loops, has been investigated as a function of maximum inductio n and frequency. According to the material grade, the domain validity of each model is defined.
