If there were a B field surrounding the beam, it would be far too weak
to overcome the Coulomb forces between the charges. Classically, it's
only at a drift rate of c that the magnetic force is equal to the
Couomb force. But here they are speaking of the force develeped
between parallel conductors.

I would point out that electrons become relativistic at very low
voltages. The Criterion is that
K> E/100. Since E is the rest energy .51 MEV that means the
relativistic cutofff is about 5100volts which is certainly below what
is commonly found accelerating electron beams.

Here again I'll note that Weber uses the term v^2/c^2, making his
equation relativistic as a first order approximation.
========================================
Hear again I'll note that nobody has given a satisfactory answer
to the idiotic relativistic fuckin' drivel
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same:
