Entropy Engine

I am wondering if a minto wheel using dichloromethane would be a good way to make this work.   Magnets at the bottom would make the dichloromethane expand making it heavier and it would fall to the ground, warm and then rise up again. Replace warm water with permanent magnets.     Maybe need to have dozens of glass capillaries depending on the time it takes to change the temperature of the fluid.

Thank you for idea. I think, this model should be proved first.
All opinion of experts are welcome.

I added new model with short temperature range around Curie point. I think, it should remove some questions about possibility of implementation of this idea.

ok so,.. 10T field,
put the alloy inside, and...

+12 degrees?

hmm....

Thermal conductivity,...  add a heat sink.
scratch the bird, just leave the metal IN the field....

take the heat off as it is generated, until magnetic equilibrium is reached.
Heat energy = x

remove field....
heat goes back in...until  more than we took out when it heated...
hmm....

Cold Energy = -y
Difference in T = -y + x

Use this difference in T to drive an external expansion process.
gas must be chosen appropriately for change in T, with respect to ambient.

closed system, sterling-type.

using heat-sinks, or external heat/cold reservoirs, we can drive a heat engine,
without respect to the rate of change of T in the alloy.
give or take...

all there is left to sort out is the application of the field to the alloy.
perhaps a solenoid, or timed-cam shaft that activates every 60,000 rotations or something....
(not literally 60,000... that was just an arbitrary number I threw out as an example,
    the actual value would depend on the system, rate of change of heat in the sample, vs mass, etc.
      as well as the capacity of the heat reservoirs, size of engine.)

You maybe right smokey.  If you can have an area inside a magnetic field with a higher temp than an area outside of a magntic filed why wouldn't you just use a peltier electric generator to use the temp difference between the two locations to generate power. Or if you must ye old sterling engine.
