Magnetic Jigsaw Puzzle

Pieces look the same but just don’t go together
  [vote for,

Watch as pieces spring off the backing or away from each other. See them flip in your hand. Rare earth magnets make this possible.

       They're called rare because they're not cooked.

       Exposing a magnet to too much heat makes them lose their charge while at that temperature. So I guess they should not be cooked.

       Rare earth magnets are made from neodymium, a rare element which is difficult to purify, instead of the usual ferrite magnets, which are primarily iron and boron.

       Magnet tartare.

       This idea is repulsive. I like it. +

       clever idea - but I'll have to vote against it because I can't imagine any pastime that would be more annoying than trying to finish one of these.

       I s'pose a nonmagnetic 4 piece puzzle would be alot less annoying to solve. :P

       (For the sake of completeness: [Cedar Park], terbium is also a widely used one (terbium iron boron), and cerium (cerium magnesium nitrate), and there are a few others in close proximity that are useful.)
