You have failed to tackle the real question. If we have say a permanent magnet, and a C core, as we pass the magnet into the C core, an inductive field is established.
If the inductive field will also effect the atoms, and if the material is aligned, then the aligned atoms will have energy induced into and out of them. I think that the effectiveness will depend on the form, the larger the diameter the less voltage would be induced on the atomic scale. Anyway, the question is if you manage to induce enough of an EMF on an atom (the nucleous or the electron shell, or both depending on what is aligned), what would result? If that EMF assisted the movement of charges making a magnetic field, what would happen? If that EMF opposed the movement of charges making a magnetic field, what would happen? Opposition would occur as a piece of steel was being magnetized, a generator does this, is there a 'tax' on the iron in a generator? As the magnetic field collapses it regains energy. If we took only the current that occurs initially and left the iron to 'absorb' the energy from the demagnetization, what would occur?
