“…Standard BH curves and iron loss measurements are normally made using a square-shaped stack of laminations called an Epstein frame [10]. However, other core shapes, such as Rowland rings [3,4,11], can also be employed to demonstrate the curve on an oscilloscope. In figure 1, the toroid shaped core we have chosen for this work is shown with a type of circuit that is suitable for obtaining a BH curve (i.e.…”

Measuring the magnetic hysteresis loop and energy loss characteristics of magnetic materials helps students to understand the ferromagnetic properties of the materials. In this study, a conventional experiment is combined with automated image processing to learn about the fundamentals of the hysteresis loop by measuring its area. We process a loop image acquired using a digital camera to calculate the area. The results of this easy and instructive experiment are substantially compatible with theory and are more precise than those obtained when using the tedious conventional method of manually evaluating the loop area. The proposed method is discussed as a clear-cut and a fast tool to reproduce the results with pragmatic accuracy.

“…The use of a dataacquisition system makes these measurements more informative, and the data collected can be used to study the properties of ferromagnetic materials. [3][4][5][6][7][8] We use the ScienceWorkshop data-acquisition system with the DataStudio software from PASCO scientific. In addition, we use a 1600-turn coil (PASCO SF-8612), an O-shaped ferromagnetic core (PASCO SF-8614), and the Signal generator incorporated in the ScienceWorkshop 750 Interface to feed the coil.…”
