B-H Loop of Sintered Stainless Steel 410 Adjusted by Superellipse Model

B-H loop obtained from frequencies higher than 40 Hz can be satisfactorily adjusted by Superellipse model. Examples of application of the Superellipse model for sintered stainless steel 410 are presented. The parameters of model (four parameters) may have assigned physical meanings that reveal magnetic behavior, such as coercivity and remanence. Furthermore, they are directly related to the aesthetics of the B-H loop. The Superellipse model is very versatile, describing the most closed shapes (rods) and the more open (rectangular). The obtained parameter values reflect the magnetic variability of sample. In addition, by applying the model it was possible to analyze the magnetic and structural properties of a sintered stainless steel sample.
