Question:
Can you demagnatize an 150 degree aluminium casting down to at least 90 degrees in a matter of seconds by using induction cooling? If so, what type of demagnatizer needs to be used?



Replies:
Aluminum is not a magnetic metal, so not much would happen I don't think, except maybe generating some eddy currents.

You can find out about a related topic by searching the term: "adiabatic demagnetization" on the Web. or "W.F. Giauque" who won the Nobel prize in 1948 for perfecting the technique for producing temperatures less than 1 K.
