Thermomagnetic (Curie-point) transition
Heating a soft ferromagnet through its Curie temperature collapses its magnetisation; cooling restores it. Cycling a magnetic circuit between hot and cold regions changes the flux through a coil.

Relations
- a soft ferromagnet with its Curie temperature between the hot and cold reservoir temperatures (Gd ≈ 293 K)
- the element must be cycled between the reservoirs, so a heat-switch or motion is needed
Matrix context
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
