interesting glue phenomenon
i use 2ton epoxy to glue my glass magnets to rare earth magnets.

I had a few of those little (10mm) rare earth magnets around, and needed
some refrigerator note holder-uppers. So I decided to glue a few chips of
granite to the magnets.
One attempt w/ Duco Cement didn't cut it. So I decided to try the "J-B
Weld".
I mixed it up according to instructions, put a dab on the rock chips, and
went to press the magnets into the glue.
As the magent approached, the dab of glue actually lifted off the rock
chip
(like a sunspot) and glommed onto the magnet. I pushed the magnet onto
the
chip and waited for the stuff to dry. Before it dried, though, the magnet
sucked the glue out from between the rock chip and the magnet, so that the
glue coated the magnet's surface. I'm not sure there's enough left to
hold
the magnet to the rock chip.
I guess there's some iron in J-B Weld. And those little magnets are
pretty
strong.
