Repairing a dented tuba with magnets

Really: be careful. Strong magnets are extremely dangerous. I once managed to get a 1" cube of neodymium stuck on either side of my hand for a few minutes.

Think this is the very first thing anyone does when handed two pieces of neodymium. I know that I did this within a minute of my first experience with two free and loose neodymium magnets. I watched many others do it too. The look on one's face is always of shock and disbelief that this magnets were so strong, mixed in with the pain, even though you warned them before.
