This is the reason why copper is diamagnetic, there is one orbital spinning sink e-
But imagine how powerful a magnet could be made if we were able to align all the atom's electrons... magnetism relies upon only unpaired electrons, and the rest of them orbiting the nucleus give no net increase of the magnetic field.
So when , as was telling Joe , the circuit is closed , the dipoles between the slab of the battery , make the aether to flow all around , and towards the circuit, to neutralize the charges ( positives go to neg-slab and conversely , which discharges it ) , and this flowing in the copper matter aligne all the alone e- on the copper atoms in the same direction, which induces magnetic dipoles on ALL the copper atoms in the matter of the coil , which as for effect to create a magnetic field, similar as one we find in a real neodynium magnet , H.
This field take a certain time to establish in the entire matter of the coil, t ~ L/R , relaxation time of charges in a coil with inductance L and R as resistance .
--> if L=200Henries and R= 20Kohms, t = 1/100s = 10-5 ms
So we have two currents , as Maxwell told in his 1861 paper on E.M : Jtotal = Jconduction + δD/δt , where Jconduction = U/R and D is 'Displacement current' as Maxwell named it.
But today, this is considered as null in the calculus of currents in a circuit , and it is considered only in the caculus of wave propagation in void. This is why Newman is right when he said that J = j + j - he named it X+X in his book.
And this is why Newman was right.
The remaining difficulty is to 'catch' it his current BEFORE it is suppressed by the bemf. The reason is that δD/δt is extremely rapid, it is the speed of c . We see that in the second and fourth equation of Maxwell paper :
2 - ΔxA = μ.H ----> the A is the 'electrotonic' pulse of Faraday ( this is what Newman call with his humour as a catcher fighter 'the punch' )))))
4 - E = μ.v x H - δA/δt - ΔU ----> and the effect is the negative bemf : -δA/δt which arrives immediately or quasi, in opposition, minus sign, to the emf E ( U is the gradient potential furnished by the battery )
This is MHO to help understand the physical Electromagnetic model of Maxwell which has been suppressed since relativity in all universities,
and which explains why we CAN pump in the sea of aether, theoretically.
