Also per Wikipedia, the Curie point for iron is 768 C. That's over

The Curie point of iron is irrelevant. However, I am quite surprised
to see the Curie point of Nd-Fe-B magnets is 320 degrees C. I
thought it was much lower. I've destroyed magnets with heat, but I
don't recall what kind, or how. Maybe soldering.
