Magnetocaloric Refrigeration Wheel (2D)

This simulator models a rotary active-magnetic-regenerator refrigerator: a ring of magnetocaloric material spins continuously through a fixed high-field gap between two magnet poles, rendered here as a top-down 2D schematic. Each block of material heats up as it enters the field and cools as it leaves, exchanging that heat with a hot reservoir and a cold reservoir once per revolution — the same working principle used in prototype room-temperature magnetic refrigerators built around gadolinium alloys. Adjust the applied field, the material's Curie temperature, the wheel's rotation speed and a parasitic cold-side heat load to see the hot and cold reservoir temperatures diverge in real time on the strip chart, and watch the magnetocaloric effect collapse in the adjoining Gaussian-peak panel when the Curie point drifts away from the wheel's operating temperature.
