Besides using magnets for holding canopies and wings to fuses, I realized that I use magnets for a lot more. From broken magnets from some old motors to Neodymium Magnets. Here are just a few uses:
Calculator
Shopsmith tools and wrenches
Chuck keys on my Smithy -- Well worn...
All my grinding and buffing disks
Rules (many different places around the shop)
Different items stay on the top of the toolbox even when open 
Adjustable wrench
I even use a magnet instead of a door stop to keep my shop door open. (No
it's not a wooden door).
That's just one half of the shop...... Bet you have many more places to stick things...
