This reply is only geared towards the comment regarding the energy it
takes to magnetize with respect to permeability. I will respond to
the excess MCE energy later:
It is a misnomer that it takes half the energy to generate the same
magnetic field within a mat'l of twice the permeability. Lets first
use a coil/core as an example. The greater the permeability of the
core, the higher the inductance of the system. The higher the
inductance, the more voltage is required to generate the same
magnetic field, albeit with proportionally less current. The energy
consumed by the coil is the same regardless of the core permeability.
Another way to look at it is to identify the force it takes to detach
a magnet from a piece of magnetic mat'l. The energy inside the
magnetic mat'l due to the magnetizing field is equal to the energy it
will take to seperate the magnet from the mat'l over a distance until
the force of attraction equals zero. This energy rises with
permeability, because the force vs distance increases in proportion
to the permeability.
I would like to stress that if permeability increases, it takes the
SAME amount of energy to generate the same field within a mat'l of
the same dimensions.
Now regarding specific heat, what mat'ls show a rise in Cp under
influence of a magnetic field? Because I would be inclined to think
that they cool, instead of heat.
