So, the purveyor of the electromagnetic force is the photon, as in visible light and radiation. If you look into it you find talk of “virtual photons” being the purveyors of magnetic force, but it seems they are more of a mathematical construct, and if you read enough about it, it becomes clear that it’s a whole lot of technical language that boils down to, “we dunno”.
Pretty much everything in the primordial solar system orbited in the same direction and the same plane, and that motion is conserved to this day, for the most part. The moon would have had to have been captured for its rotational energy to be that different from that of earth’s.
