Rare earth magnets.
I recently purchased four 1/8" rare earth magnets (from Radio Shack, two packages of two) Like a dummy, I lost them on the living room carpet, thanks to an unplanned sneeze. Well, I finally found them today ( a week later).
All four were neatly stacked together, with a death grip on the carpet.
I finally got them out of the carpet, and pulled them apart. No magnetism...
I checked them against a more conventional magnet, and the magnet wouldn't even pick them up...almost like stainless steel...
What happened? did they cancel each other out? Or did they lose their magnetism (in a week?)
Right now, they're sitting on my desk, four little non-magnetic hockey pucks...
Anybody got any ideas?
No good deed goes unpunished.
