Abstract
In this article it was studied the magnetic influence of an electromagnetic coil on the measurements, realized with a single strip tester. One major difficulty in modeling of the magnetic materials is the magnetic hysteresis. As a consequence, it was used the Frohlich-Kennelly model for defining the hysteresis of the soft magnetic material, from which is manufactured the magnetic core of the electrotechnical devices. A numerical study, based on finite element analysis, is proposed in order to model a Single Strip Tester (SST). For this it was made a geometrical description based on technical data of a SST developed by Brockhaus Messtechnik, which measures magnetic properties of silicon iron strips with an area of 280 × 30 mm2.
