Hi,

I'm not sure whether or not it represents stored energy, but if you
multiply the
MGO of a magnet by it's volume, you get a number of Joules (it's not
much BTW).
How much? If we dissolved magnetic material in an acid, compared with
dissolving the same weight of the magnet material, unmagnetized, same
other conditions, could we measure a temperature increase for the
dissolved magnetized material vs. the dissolved non-magnetized
material? I do assume the energy would end up as heat. If it's a
reasonable amount of heat, this would make a nice science fair project.
