Why do hematite magnets buzz?

Question

Is it because they're spinning? If someone could direct me to a good website explaining the physics behind the sound I'd be forever grateful! :)

Answer 1

Hematite is not magnetic, magnetite is. Hematite does not buzz. I have seen many specimens of hematite but have never heard one buzz, much less spin. In fact, I have never heard any mineral or rock buzz or spin.

Answer 2

Buzz? how many magnets do you have?

If you have two magnets colliding against each other, then they are buzzing because they are bumping together and vibrating...
