Thermomagnetic convection —couples to→ Electromagnetic induction

Conditions

• magnetised ferrofluid advects through a closed loop wound with induction coils, so the flux linked by each coil changes as magnetised packets pass
• a permanent-magnet bias field keeps the fluid magnetised where it moves past the coils

This claim does not itself create a matrix cell. The context below belongs to Thermomagnetic convection, the phenomenon it is about.

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.
