Anyone who has Java enabled on their browser can play around with the Ising magnetic simulations, a well known and popular way to simulating magnetic materials. Give your browser ~ 30 seconds to get the applet going. You’ll see a large window. Change the “disorder” to a square loop core, ~ 2.3. Click “Generate loop.” Then click on BH curve to move the applied field. Moving the field back and forth from full to 0 to full to 0, etc. matches the core seen in the Steorn power in & out scope plots. You’ll see how it shows that most of the energy stored in inductance in the Steorn setup can be captured back, as shown in the Steorn scope integrated power plots.
