Hi Jared,

Comments intersperced,

True

No so.  Etotal = 1/2  L Isqrd as above.  Fields and particles are one and
the same thing.
You cannot double count them.

Einstein said it is a delusion to think of the electrons and
the fields as two physically different , independent entities.  Since
neither can exist
without the other, there is only one reality to be described, which happens
to have
two different aspects; and the theory ought to recognize this from the start
instead
of doing things twice.

Dirac also said fields and particles are not two different things.  They are
two ways
of describing the same thing -- two different points of view.

Incorrect.

When describing waves of energy there is no need ( in fact, it's incorrect)
to invoke
masses at relativistic velocities to describe the wave nature of matter.  In
1923 DeBoglie
applied Einstein's 1905 postulate (W = hw) to the energy, W, of an electron
wave, and
identified momentum,p, of an electron.  Energy and frequency,w, are the same
quantity.
Electrical momentum,p, is not related to Newtonian mass at relativistic
velocities.

I have noticed you often try to cobble together different physical
equations in an attempt to produce other equations that the physical world
is supposed to adhere to.  Unfortunately this rarely works.  It's best to
test your theories with experiment and if successful then apply the
algebra to your data.

I do find your ideas about quantitization of magnetic fields in coils to
be quite interesting. Actually there is good experimental evidence of
macroscopic quantum behavior in certain coils.  I suspect it may be
related your findings.  Contact me off line and I will give you a citation
about quantum foundations of electromagnetism.

Hi: RWW



No double accounting involved.  All flowing currents will produce magnetic
fields  equal in energy (a fundamental fact that few people seem to
understand). If it were not so, the consequence would be energy  that tends
towards infinity. (see Lenz law!)



You must consider that the force against the wire is a  Newtonian
force.  Newtonian
forces do arise from relativistic mass. In fact as we speak pressure is
being exerted against your very person by energy waves that have been
traveling through the cosmos for longer than I can remember.
