No, the leading edge of the mechanical transfer of power - I was trying to make a faux comparison that electrons would be the inside of the shaft/cog & the fields the leading edges (that transfer the power & are moving more).

I mangled the comparison, should have given up on it. Vibes are hard to compare with anything non-vibes.

Great youtubing in the links, that's how you get them views (benefit several creators and spread science)!
(*I just skimmed them for the general vibe, I'm not voicing support in case they are weird ppl, I don't know them.)

Edit: while speeding through I noticed a very cool simulation (software), yt/mcez0ri9yPY, these are very neat visuals.
