Display MoreThe infinite = circular solenoid is a good approach.
Now you only need to 180 degree change the logic. Charge is at rest as EM flux moves at light speed and the only force that remains is the Lorenz force.
EM flux inside a particle is fully bound so there is no infinite B field - just the flux lines = main part of EM mass given as Lorenz coupling.
In fact in the new SO(4) model everything is 180 degrees opposite to common thinking. It will take some time to get a good feeling.
Charge alone can never move at high speed as real charge needs a carrier (e,p). So charge moves with particles.
But as there is some symmetry you can use current loops to get some quantities.
So try to get the electron g-factor as done in :: https://www.researchgate.net/p…oid_Model_of_the_Electron
Bump again as it looks like all constants used to calculate properties of the electron given Maxwell are the introduction of maxuimum B field and E field this is interesting as
it implies that there is only 2 free parameters extra but we have 3 constants $h,me,e$.
