BEP, I remember you stating once that your training including and additional field. I thought that it might have also included how the magnetic field is created that drives the electrons/ions to create conventional current.
Yes. I think you also know I don't usually bring it up as it can start fires
There is no doubt there is a third field (I still doubt 'field' is a proper description as 'field' is only a measurement of something, not that 'something' itself).
Folks always speak in terms of straight line movement. There is no such thing. When I mentioned 'charge' above I'm speaking of two things. Charge is normally thought of as a difference in potential. It is but it is also the spin of that potential. I think this is why a static charge can move a compass needle.
There will be no magnetic field unless charge has movement. Movement cannot happen without time.
If we want to create a usable current flow in a conductor we need to really understand things like induction. I don't believe the common book description is correct as the base theory uses itself to prove itself.
An EM wave is shown as two fields perpendicular to one another, magnetic and electric. Both are depicted and thought of as sinusoidal lines. This wave isn't the lines. It is what is between the lines. If you can think of it this way you can see an EM sine wave is - at its base - a series of compressions and decompressions. When you have two perpendicular fields you will have angular momentum. It is well known in radio propagation that a transmitted signal always rotates.
So does current flow in a wire and the magnetic field around that wire.
There would be no rotation without a third field. Call it what you want.
There are three basic fields in nature, which manifest mathematically as gradient, divergence and curl, or; tempic, electric and magnetic.
When you understand this you should have a real understanding of why the speed of light can be varied just by the mass it travels. Lately, to the point of taking several minutes to transverse a few feet of crystal. The speed of light is constant. The overall tempic is not constant to the traveler. Only the local tempic is constant to the traveler.
We also need to understand the difference between particle velocity and group velocity. After all, the group velocity of a charge or magnetic field change can do the same as change of velocity of a charge or magnetic field.
Then you get into so-called 'left-handed' actions. This is nothing more than the group velocity being the reverse of particle or wave velocity. You have seen it when watching a fan turn. At some point the blades appear to run backwards. That is negative group velocity. Group velocity can also be far more than velocity of a particle or wave.
So there you have it. Drift current is incredibly slow. It can be mm per second while the force can be seen almost instantaneously at the other end of the wire. This is line charge.
You also have surface charge (skin-effect) and spatial charge (dielectric charge). Of the three the latter is the biggest speed demon. It will not be deterred by a magnetic field as easily as the other two.
This leads into the 'cancellation' thoughts. Total cancellation of a magnetic field is not possible, or is it? If it is then the total absence of a magnetic field means that space must be filled with spatial charge. Parametric pump perhaps?
So, yes. We need to go back to basics. But we must understand what those are.
My comments are not derailments of thought. To me it is just the way it is. The interaction of fields is the ultimate answer.
We also need to stop thinking in linear terms. A toroid is not a straight line. Circumference requires the use of pi in the math. If you want pulses on the control coils to meet those on the collectors you must use pi or they will never meet.
Sorry about the big wind. Must be the coffee
P.S.
I see we are back to basics
Insults, name calling, etc. It is good to see things are going back to normal
