I ordered, on the net, a selection of nickel plated rare earth neodymium iron boron magnets (NdFeB) from 'Amazing Magnets' in California US. Boy, are they powerful! And very helpful people, the stuff came air-mail within a couple of days, 6000+ miles. The magnets are really strong, so you have to take care with them. Currently I have some 1/2" x 1/2" ones stuck on the inside of a metal file cabinet drawer. I have nowhere to 'slide them off' to, but I'm workin' on it. ( Seemed a good idea at the time, what an idiot! ) Cheap too, and in the shop I'm using them to hold chuck keys and other tools handy to the relevant machines. The weight that even a tiny one will support is absolutely astounding.
