PP at this level of exploration it is no use at all to use scientific buzz words like "magnetism". You have to define exactly what magnetism is if you are going to use it at this level of inquiry.
Now as far as I know no one has actually ever stated exactly what "magnetism" is ever! Sure they have called it all sorts of things but never have they described what it actually is. Same goes for gravity. Gravity is just a buzz word until it is defined in a way that states what exactly it is.
ZPT defines gravity as dimensional collapse towards the zero point. Dimensional collapse means that the volume of space is collapsing from 3 dimensional to zero dimensional constantly according the inverse square rule etc. being held out [using your words] by the inherent momentum and energy [time] in the universal system.
Magnetism is a bit more of a head spinner so I wont go in to it here...
They are already explained in this thread. Their physics are explained. Remember that I came up with the gravity physics 10 years before science with black holes in particles. I made a big point of it.
