it was recently pointed out to me that electrical generators don't actually generate _electricity_ since energy can't be created or destroyed. they convert energy. but then, what are they generating?

generators are sources of _low entropy_, in the form of electric current, and I'm still trying to wrap my head around that.


@ashfurrow I tend to remember that to keep up with conservation, whenever a magnetic field (from the rotating generator turbine) induces a current in a wire, that current induces it's own magnetic field that OPPOSES the field that induced it

It's wonky, but it provides a torque back on the generator and is why you can't just use a generator "for free"

@mdszy thanks for the analogy. It took me way too long to wrap my head around why grounding the power grid even works, so I’m catching up to these concepts slowly 😅

At least I think I got it hahaha

@brunoph it's one of the few things I remember from my E&M fields class lol
