Yeah. That's it. Nothing fancy. The principle is the same whether it's a permanent magnet or if it's a coil of wire energized by the battery.
That's my point. Nothing has fundamentally changed since the 1950s for home auto repair.
My editorial is that anyone who claims they changed is usually someone who doesn't (and never did) understand them, since the mechanics is the same.
I haven't had an all-electric (or even hybrid) though, so since I'm ignorant about them, I won't say whether they (finally) change things fundamentally.
The minor stuff some people talked about (such as fuel injection replacing carbs) usually made things easier.
Most of these people who never understood cars in the first place are the ones who claim they can't work on them because they're "computerized", which is just complete nonsense, imho.
Just as the most ignorant people on the "vaccine" are the ones telling everyone else what they should do, the most ignorant on cars are the ones who are saying that they've changed so much that they can't work on them.
All they're really telling us is they can't work on cars, and that's OK. But it's not the car's fault.
