🧲 Ferromagnetic Hysteresis B-H Loop (2D Preisach domain model)

2D B-H loop of a magnetic material driven by an alternating field: change amplitude, bias, coercivity and domain spread, see the loop trace out, the domain relays flip and the energy lost per cycle. Same Preisach engine as the 3D page, with checks of loop area, symmetry, remanence and coercivity.
