The latch on our clothes dryer broke; the door would no longer snug up and maintain the seal or necessary pressure for the safety switch. I now have a 2x2x1" rare earth magnet holding the door shut against the dryer frame. Its strong enough to keep the door snug, but I can still open the dryer door with a good tug.
I'm not sure why I had a 2x2x1" neodymium magnet laying around, but I'm glad I did.
It is interesting that with the neodymium magnets being rare earth materials and apparent limits being placed on their mining/import/export etc., the price of them has sky-rocketed. There was a time when all the bass cabinets for bass players were getting smaller and smaller and lighter and lighter thanks to these magnets because it meant you could have a smaller speaker driver (hence less weight) but now they're having to resort to the heavier speakers again.
A shame really! I never did buy any light cabinets but always wish I had! At least Class D amplifiers are doing the rounds and so massive wattage amplifiers are now tiny and lightweight.
