What is the difference between rare metals and rare earth metals?

Rare metals are simply metals that aren't common. They don't necessarily have any chemical properties in common. (Many of them do, because they tend to cluster in certain regions of the Periodic Table - around iridium and rhodium.)
Rare earth metals are, specifically, the lanthanides (scandium and yttrium are also sometimes included, because they tend to be found in the same mineral deposits where the lanthanides are found). They tend to be very similar chemically, to the point where it's actually difficult to separate them by their chemical properties.
The rare earths are not really all that "rare": with the exception of promethium (which has no stable isotopes), they're considerably more common than the truly rare metals. Gadolinium is, for example, about a thousand times more common than gold.

What is the difference between a magnet and a rare earth magnet?
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.
