PhysicsProf Steven E. Jones circuit shows 8x overunity ?

[profitis]

Take a lump of gadolinium on a cool day (19 deg c),shove it under a magnet..the gadolinium jumps up,collides with the magnet and heats up a bit over 19 degrees c,its curie point,what happens now?what happens now?what happens now?wooooooooo...spoooky

"This new approach confirmed that the relationship between the maximum adiabatic temperature change ( ΔT peak) and the applied magnetic field is perfectly linear".

Aeronautics Corporation has now demonstrated the first room temperature, permanent-magnet based rotary magnetic refrigerator. The rotary design consists of a wheel containing gadolinium and a strong permanent magnet. The wheel passes through a gap in the magnet where the magnetic field is concentrated, and the gadolinium heats up. While still in the field, water is circulated to draw the heat out of the material and reject the heat through the hot heat exchanger. As the material leaves the magnetic field, it cools further. While the material is out of the field, a stream of water is cooled by the material and circulated through the refrigerator's cold heat exchanger, removing heat from the object to be cooled.

Here's a video that shows non-latching too...  (tape wound core doesn't hold field)

Part 2
https://www.youtube.com/watch?v=BsN2sr3U0PY  (has a bit that transfers the 'holding' energy from the secondary back to the primary)
Also shows that the resistive loss in the wire eventually kills the current in the closed-loop secondary ...


And some flux gate switching https://www.youtube.com/watch?v=L9HyyGdnmb0

Adding the magnets to the C core, as in the flux gate switching video, would double the adiabatic heating and cooling of the lower core, for the same latching and demagnetization cost! The graph above shows that doubling the magnetic force, doubles the temperature differential!
