That explanation works as long as you are happy to ignore the acceleration phase and just consider "before and after". There are a number of complications during the acceleration.

Yes. Note that this is a highly unrealistic electron drift velocity. Typical speeds are around 10^{-5}m/s, yielding a separation change of around one part in 10^{26}.

I disagree. As was pointed out earlier, you needed other people (using the mathematical formulas) to tell you the strength of each interaction. Your approach can help you understand the math, but it simply cannot substitute for the math.

It is not only inefficient, it is also insufficient.

But I am not the one who said your graphs were wrong, that was you. I am just telling you why: they are wrong because they are the outcome of a fundamentally flawed approach.

Another fundamental flaw of this approach is that you are attempting to “explain electromagnetism with relativity” when you don’t know relativity. How does that make sense as an approach? In order to avoid learning electromagnetism directly you are now trying to learn general relativity, but general relativity is a substantially more difficult subject.

If an advanced second grader asked you to explain multiplication tables using logarithms when they don’t know logarithms, would you not recommend a different approach to multiplication?
