Hysteresis:
The magnetic state depends on field history — irreversibility from domain wall pinning.
B_r (remanence):
B at H=0 after saturation
H_c (coercivity):
H needed to demagnetize
Preisach model:
Material as superposition of bistable switching units (hysterons).
Energy loss:
∝ area enclosed by loop (per cycle).
