Jun 08, 2013· Rare earth magnets for fun and profit Review date: 22 September 2001. Last modified 08-Jun-2013.. One can academically appreciate the fact that every electric motor in the world (not counting a couple of very impractical ones) works because of magnetism.. One can reflect on the fact that every transformer uses it, too.
