Veritasium -- How Special Relativity Makes Magnets Work.
TimFox:
I'm approaching my limit rapidly.
I made my recent posts because I feared that a reader not familiar with the topic might believe that his un-supported statements that no one had measured the magnetic field around a charged-particle beam had any truth to them.

I have to say that I admire your patience and and continued good humour when engaging with aetherist, who clearly isn't here to learn but merely to tell everyone they are wrong about everything. A lesser person would have said harsh words and/or left to pursue an actual worthy cause many, many pages ago.
In fact, the only reason I am still watching this is to find out exactly where your limit is >:D

I'm waiting for the announcement of the published paper on the electon, this new world changing discovery, and also whether tin foil will protect me from aetherwind. Though maybe I simply need to change my diet. :popcorn:

It may be a while before it gets through normal peer review, unless they use abnormal peers.

In a particle accelerator, one can compare the current with these magnetic sensors to the current that hits a Faraday cup (which suppresses the effect of secondary emission from the target).
Have you ever seen a particle accelerator, or read anything about them?
What do your countrymen at the Australian Synchrotron Lab say?
PS: doing some elementary Googling, I found an interesting engineering thesis from Georgia Tech back in 1962: https://smartech.gatech.edu/bitstream/handle/1853/14924/lineberger_william_c_196212_ms_69818.pdf?sequence=3&isAllowed=y
The author discusses practical methods for measuring the magnetic field induced by a beam of charged particles without interrupting the beam. Since this was already a physical phenomenon applied to practice in engineering, no one needed to crow about it.

But, if the magnetic field of a steady DC electron beam in vacuo (in a glass tube) is equal to the magnetic field of the wire supplying the steady DC, then this falsifies the STR explanation (ie that it is due to the length contraction of the wire), because there is no wire for the electron beam, there is only vacuum.
The vacuum contains spacetime, & i suppose that Einsteinists could claim that the space of the spacetime contracts, but that would i think require that the electrons spacings also contract, which would give the beam a double dose of negative charge, which is the opposite of what Einsteinists are looking for.

A 2 page paper would do the job. Based on one little X involving the speed of electricity along a threaded rod compared to a plain rod. I would do it if i had access to a good scope.
Electons also hug a nucleus. Electons "orbit" a nucleus, electrons dont orbit.
Here the hugging force is due to the slowing of em forces near matter (ie protons & neutrons of the nucleus here)(the Cu of the wire in the case of the wire), plus the attraction of the protons (in the nucleus here).
