Today, we know that magnetic fields are generated by the spin (on its axis) of electrons, and that the electrons continue to spin whether or not the magnet (magnetic field) is put to work. We also know that permanent magnets can be made to do (mechanical) work for long periods of time and show little or no decrease in magnetic strength.

Given that all permanent magnets must have at least two poles (one North and one South), their fields are therefore unevenly distributed, polarized in shape as well as charge. Accordingly, it is not difficult to imagine that two magnets might be capable of doing more work when pulling themselves together (or push each other apart) along one path compared to another path. In other words, magnets can be made to pull themselves together (do work) along a path where the magnetic field is stronger (resultant force in the direction of motion) and then the magnets can be pulled apart along a path where the magnetic field is weaker.

Permanent magnet motors are not examples of perpetual motion. Instead, the magnets provide a source of electromagnetic force which can be transformed into mechanical energy. The electromagnetic force comes from the spin of electrons (see below for models of electron self-energy and spin) which is described by the scientific community as "intrinsic". As early as 1921, Otto Stern and Walter Gerlach performed an experiment which showed the quantization of electron spin into two orientations. This made a major contribution to the development of the quantum theory of the atom. Simply put, the magnetic force and the mechanical energy generated by permanent magnets is an "atomic" energy released continuously from the electrons. More recently, quantum physicists have many speculations about the source of the spin and related energy. Nonetheless, the spin is real, the magnetic force is real, the work generated by magnetic force is real, and magnetic fields of permanent magnets can be unevenly distributed
IMO you are not going to get much response on this topic. You are are on the wrong forum for discussing 'electron spin'. We are interested in making wheels spin, I for one care less about electrons, atoms or planets for that matter.
The combination of magnetism, elastic forces of the spring and gravitational pendular forces, might lead to a small release of zero point energy, maybe enough to be utilized for work...
Newton's laws must be interpreted in the light of Einstein's relativity and as such there exists a time lag between action and reaction that could be exploited for use to generate an asymmetry condition allowing for release of heretofore undiscovered energies and a potential perpetuum mobile...
Perhaps by using mumetal or something similar, a horizonally rotating magnetic shield could cause an iron ball bearing to drop, which presses a lever, which causes re-rotation of the magnetic shield, which will allow the ball bearing to be lifted off the lever, starting the cycle over again...
