Permanent magnets do in fact store some energy, place the magnet within a coil and connect a load to it, if you cause the magnet to demagnetize by some means the collapsing field induces a current in the coil and power flows into the load.
I think we need a scientist here I am only a technician!
If that is the case, then one answer is the atomic alignment, but that doesn't really explain the source of the fundamental force either.

There's not a lot of dispute that magnetic materials are somehow drawn towards each other. Is this because of an attractive force, or is it due to the absence of some repulsive force?
It's the electromagnetic field interacting with charges that either pushes things apart or pulls them together. This field can either attract or repel--something that's due to the fact that the field is generated by, and interacts with two kinds of charges, +/-. A field acting on uncharged matter will produce no force, and you'll also get no force if you have charged matter, but no field. Is that what you were asking about?
I think JP has already confirmed my hunch that the force is mediated by virtual photons.
Bungee cords would also use virtual photons to transmit the forces between their atoms.
Virtual particles come about by trying to simplify these nasty expressions by extracting the most important contributions to them and writing them as something more intuitive.
such as a stone taken to the top of a building - it has gravitational potential energy, but the energy had to be supplied by the stone being carried up in the first place.
