thermodynamics of cores.2nd law breach?

@pw..aha,but why didnt you bring into question the temporary splitsecond increase of magnetic domain alignment in the cooling gadolinium when you suddenly removed your magnet.this happens extremely fast in a inductor,all at once when current cuts off.cooling happens so dramaticaly fast that if you took a snapshot of that moment you would see the domains even more aligned just prior to collapse than when they were created.

And with this post you lost me.

Just as the rate of heating would be during the magnetization phase, I would think that the rate of cooling during demagnetizaton would be dependent upon the material's thermal mass, thermal conductivity, and the thermal resistance to the environment.

Good luck with your experiments...

@pw let me put this to you another way.the domains in the inductor core that have cooled down in front of the incoming devastating heat wave align to more order prior to their disruption.its as simple as that.magnetic field strength increases with decreasing temperature,this is pure fact.the degree to which this happens will depend on choice of core material.collapse happens much faster than buildup.buildup happens against a resistance,collapse happens with the resistance(rubber band,gas-piston).

@pw..picture a shockwave of heat moving from one end of core to the other end,each and every domain undergoes drastic cooling and increased order just before it is destroyed by the incoming heat wave. All this happens on our kickback stroke of the thermodynamic cycle.

@pw..try compress a gas,then release it,you will see what i mean.the decompression happens at a explosive pace,and so does the cooling.
