comment Circularly Magnetized Neodymium Torus With Minimum Flux Leakage
So am I to take your response as implying a sustained current, while cooling below the Curie temperature to anneal the field lines isn't as important an instantaneously higher current above the Curie temperature?

comment Can Charged Virtual Particle Interactions Propagate Electromagnetic Energy?
I think it goes to 0 because if it does not go to 0 then energy propagation can occur through the following mechanism: If there is a "sea" of charged virtual particles between two charged real particles whose HUP-allowed existence overlaps in time, the real particles can have a Coulomb interaction that is, in part, mediated by a chain of charged virtual particle interactions connecting the two real particles. Indeed, even if it does go to 0 at some finite distance r, if the spatial density of virtual particles is less than r, such a chain can be constructed.

comment Can Charged Virtual Particle Interactions Propagate Electromagnetic Energy?
Is one justified in claiming that the reason electric potential goes to 0 (as opposed to 1/r) over a very very short distance r is due to: t = the very very short time the HUP permits the charged particle to exist, 2) the electric potential propagating at c and, 3) the propagation of the electric potential at r=t/c ceases since its source charge "never existed"?

comment Can Charged Virtual Particle Interactions Propagate Electromagnetic Energy?
When you say something reified by a physical theory "is a mathematical expression" and further qualify it with descriptors like "very very short" it gets rather confusing what your point is. Are you saying that virtual particles cannot interact with each other because they are merely mathematical expressions? Or are you saying that they can't interact with each other because electric potential, for virtual particles, doesn't fall off as 1/r as it does for real particles and that, therefore, there is no contradiction in claiming zero, as opposed to "very very small", interaction between them?

comment c “Propagation” in Weber Electrodynamics
Given this history goes back to the earliest days of electromagnetism it is difficult to know the provenance of possibly apocryphal claims to the effect that Weber, or his later adherents, came up with a way of modeling wireless propagation at c. Perhaps those who object to this question being here are correct -- that such claims are only endemic to "non-mainstream" partisans. It would help considerably if "mainstream" had a better operational definition. For instance, a list of credible journals would be a start.

comment c “Propagation” in Weber Electrodynamics
Maxwell cited Weber's model in a positive light and dismissed it primarily because of a faulty critique by Helmholtz to the effect that it violated conservation of energy. Later Maxwell retracted this dismissal but, presumably due to the absence of a way to describe electromagnetic energy propagation through space at c, did not attempt any further rehabilitation. This is most ironic not only because c was first described in Weber's work but because vector potential originated with Weber's colleagues and that, presumably, would have contributed to Maxwell's original equations.

Are questions regarding the history of physics inappropriate?

comment Lorenz Gauge Dipole Potentials Formulation In SI Units?
What more needs to be modified in the question to unblock it? I could re-do the derivation using spherical coordinates instead of Cartesian but Cartesian seems a better choice for what I'm trying to do, which is not only rotate the Tx dipole for an antenna pattern, but rotate the detector, which is basically a test charge with a velocity vector so that the motional term(s) can be added.
