Then you're the guy who could answer this: don't rare earth magnets have a really sharp drop off of effectiveness at some critical temperature? And that critical temperature isn't all that hot.
Just as a f'rinstance, like a not-too-exotic N45 neodymium, the critical temp is...what?
[looks up "Curie temperature"]
Okay, never mind. Inside the engine is hot, but not THAT hot.
