I always find this subject interesting to discuss. One could consider every piece of iron in the universe to posses potential energy in relation to a powerful magnet. Any of these iron things could be brought closer to our magnet and it would find itself subject to a force that could impart energy onto it. If the metal item were not held back by some other means such as the scale that I have spoken of, then it would accelerate toward the magnet and gain kinetic energy until it collided and releases it in the form of heat or some other energy. This process can continue for a while until just the right amount of iron was attached to the magnet. This energy had to come from somewhere and I assume that it is from the original field.
Now the question arises as to what would happen if the iron is now reversed and removed from the magnet. I assume that any energy that was extracted in the form of mechanical work would be returned by applying the same amount in reverse. The same should not be true for heat that escaped from the system as kinetic energy was converted into heat due to a collision unless we supply a mechanical input that replaces that heat energy. I guess that should be possible and if so, the magnet acts as a transformer that converts some of the mechanical energy into heat. The bottom line is that a permanent magnet contains energy due to the field surrounding and within it. This energy can be extracted with the proper technique leaving some minimum energy that is beyond our reach due to geometry. A second process can be used to regenerate the original energy field by returning what was borrowed. The important questions that we need answered are how much actual energy is stored in the original magnet and how much can we borrow? Who wants to tackle these questions?

When you pull the magnets apart you add it, when they return they deliver it. Nothing to do with what's stored IN the magnet. And even that isn't destroyed if you "demagnetize" the magnet -- you just get the domains pointing in different directions. I suppose degausing requires some sort of energy budget.
