I wouldn't say magnets store energy.

Can we harvest energy from a magnet by demagnetising it?I think that question is less ambiguous.

You just orient the atoms in random directions and the net field getting outside the north pole will be almost zero, but each atom keeps its own magnetic field as before.You can play with a set of magnetic balls to see the effect. You put all magnets together and they will be in scrambled directions, but if you use a magnet you can orient the balls in one direction and the whole set will act like a single magnet.

...why not?analogy with electricity, battery store the energy by separating positively charged particles from negatively charged particles. If they are scrambled, the energy is lost from the system.
magnetizing reserve a specific amount of energy inside a magnet. I made this thread:https://www.thenakedscientists.com/forum/index.php?topic=69591.0but no-one was able to identify where does this energy come from, so I conclude that it is a specific amount of stored energy inside a magnet or a ferromagnetic material it appears in ferromagnetic material only when there is magnetic field.and there is a relation between this stored energy and the potential energy outside, if this stored energy has a particular amount , then the possible potential energy due to this stored energy is also finite and equal this stored energy, because if the existence of this stored energy causes potential energy , then this potential energy can not exceed the specific amount of the stored energy. there also may be a relationship between gravitational potential energy and mass-energy.
That's because you never asked the question clearly enough.

It is energy c that spins outside of the magnet (causing what we recognize as a field) that attracts by the inverse square of the distance.
nothing about the magnet itself is used other than its the magnet creating the field.
Once applied it creates the fields necessary to interact with the rotor and cause it to spin.
I think I added a new view for gravity and its cause.
, in Newtonian mechanics a net force with acceleration "a" will cause some kinetic energy , No, the force and acceleration may be like the "centrifugal" force there's no change in energy unless the force move through a distance along its length.
There is changeability between kinetic energy and forceNot really, they are dimensionally distinct.
the opposite is also true kinetic energy of a moving object will cause force .No. not really.
when a moving object stops it looses its kinetic energy and a force appears
