Hamdani,I am so pleased that you are investigating magnetic force fields. We also need to explain the magnoflux spin effect of the magnetic field please.
Bored chemist, much as I hate to do this, you are in error. I have it on good authority that there is only one unicorn. Hence the correct expression is "the unicorn did it". I don't have to remind you of the rigour needed in all such scientific matters, correct units, correct dimensions and of course correct unicorn.
The magnoflux spin effect is documented on my blogs and videos.
No reference quotes are needed as anyone can repeat the experiments at any time.
Nobody is suggesting that electrons get accelerated to anything like the speed of light in a conductor.So your claim at about 34 seconds makes no sense.Were you aware of that?(That should be a simple yes/ no answer).
This has been the mainstream view of electric and magnetic fields for quite a while: Changing frames of reference can make an Electric field look like a Magnetic Field and vice versa.
The problem identified here is the asymmetric response between the movement of positive and negative charges in the wire.
Is it a problem? It's often required that the positive charges don't and can't spread out despite a Lorentz contraction. The positive charges are the metal atoms and they are locked into a lattice. Even when Lorentz contraction puts them closer together and suggests there should be increased repulsion between them, the metal atoms cannot move apart. However the electrons are not like that, they are free to move around and can spread out.
The difficulty in working with electrically charged particles/objects is that they are attracted to even neutral objects due to electric displacement. An electrically charged metal ball is attracted to the plastic hose even when it's empty and electrically neutral.But I'm convinced about the physical interpretation of magnetic vector potential because of experiments and applications of toroid, such as in toroidal conductivity meter and toroidal transformers. They produce measurable electromagnetic phenomena even though they produce 0 magnetic field outside of the coil. IMO, the physical existence of magnetic vector potential would undermine the search for magnetic monopole.
Let's make an experiment where the positively charged test particle is at rest, while the electrons in a wire move to the left at v m/s, and the metal atoms move to the right at v m/s. Will the test particle accelerate? In what direction?
It's also very hard to give the electrons an arbitrarily high velocity, they tend to have an average velocity that is the drift velocity indicated by conventional theory which is actually a very low speed. You'd need to maintain a large voltage across the wire if you want a faster dift velocity and that is difficult to do in practice. We'll assume the velocity of the electrons is low.
You said "wire" so we'll assume the positive charges are the metal atoms and they are locked in a lattice.Translate to another frame where the wire stays sill <=> the positive charges stay still.
Going back to your original frame of reference, the distance between the metal atoms would have been contracted slightly while the distance between the electrons would have been increased slightly compared to the frame I have just used. Overall there would have been a net +ve charge density in the wire and that would have created an Electric field that repelled the test particle.
However, if it wasn't a conventional wire and the positive metal atoms weren't locked into a lattice then I don't think you have enough information to proceed. If the positive atoms can move and spread out then you need to know how and that would affect the charge density and hence the electric field you would observe.
