Magnetic Wedding Rings!

Wife works in research - runs a NMR machine in an analytic chemisty dept. The field in the room where mag is kept will instantly demag just about anything.Shes has demagged just about everything you can imagine at one time or another by forgetting and not leaving it in the outer office. 3.5" floppies (yrs ago), flash drives, security badges, credit cards, drivers licenses, and etc.

Her desk is outside the magnet area and she has a 10" gag paperclip taped on the desk facing away from the magnet that is pulled up to about 45-50 degrees and suspended by the mag field that's 10' away or so. Its a very expensive piece of machinery.
