A quasi-static analysis on 0.30 mm thick Permimphy material has been performed. The samples were mechanically cut as strips with a length of 300 mm and variable widths between 5 mm and 30 mm. The experimental measurements of the normal magnetization curves in quasi-static condition and of the total energy losses as a function of the frequency were made by means of an industrial Brockhaus single strip tester (SST). A hyperbolic model, previously applied in the case of silicon iron steels, was extended for the investigated material and the width of the damaged zone due to cutting procedure was estimated.
