Veritasium's Video on Misconception about Electricity

Thanks Ray for the link,,, All I can say is that he challenges so many facts, frankly he also ignores so many principles along the lines of induction and skin effect.
All electron movements create a magnetic field as the movement of electrons create heat, I think the author is very confused.
After all Fourier developed his equation to make a better violin, does that mean that electricity is part of a violin as his equation applies to frequency and harmonics.. Hmmmm. :)

Veritasium is misleading and tricky in the way he poses the question, This guy did a simulation in Ansys that makes more sense.

It's a transmission line, and he ignores the impedances of the source load and line.

Skip to 4:30 or so if you just want to see the simulation.

This response is only showing the action of the inductance of the wire, in fact provides a very good model to understand how an inductor opposes current flow when the switch is first turned on along with the subsequent oscillation taking place.

The premise that the energy is in the field and not in the electron flow citing that in an alternating current the movement from source to load is a very poor proof of concept as it's so wrong and does not merit any further consideration, the part that is not understood by Veritasiumthat is that with AC the source electron does not need to reach the load but the electrons at the load been moved back and forward with the number of electrons to determine the energy level in the load (Sum of the charges), this is not what happens in a DC circuit, the electron flow from supply to load and return back to the supply, then we can complicate this by evaluating the initial turn on action where the stray capacitance and the inductance of the wire will act as a tuned circuit with the resulting dampened oscillation.
Vertasium should read the works of Flemming, Faraday along with Joseph Henry, then he will have a better understanding that the electrical and magnetic field are a result of the flow of electrons, that valves work using the flow of electrons, that primary and secondary batteries work due to the unequal electron charges known as Ions, that semiconductors work due to doping creating semiconductors with holes or a surplus of electrons, that when these two are combined at a junction the resulting valence layer as part of an equalizing process (Diode).

That the raise and collapse of the magnetic field is what excites an opposing current flow in and adjacent parallel conductor, even when this is two parallel wires are one loop. I am afraid Veritasium is so wrong on so many points, I wonder if this is an April 1 joke.

Here is another rebuttal video. The guy is a bit over the top, but he gets it right towards the end of the video.

He is brilliant, I agree with all of his analogies, in my rebuttal I ignored the stray capacitance as the distance of the wires is so large that the capacitance is negligible, however his explanation is more exact.
