There are some places here in the USA that sell Neodymium magnets, but not before a waiver is signed. Those things can crush your fingers into past if you're not careful. O.O

And on the subject of magnets:

  Thought that was great,  realizing again how much I didn't know.  I did hear about the rare earth magnets, may even have bought one at Radio Shack.  I tried to get more info on magnets, lots at wikidictionary,  actually to much to sink in. 
  Clear, well never mind.  at 3:35  Even better explination.

Good and educational video there Dave, thanks for posting.

And agree with Carl, there is always something new to learn, probably the best thing about the Internet.
