Rare earth magnets are powerless against chips stuck in foot.

Or worse, are powerful. You want a lens (or stereo microscope)
and demagnetized forceps. A magnetic field is likely to
exert torque, and not in a pleasant way.

My usual problem is in/about the fingers, for a foot chip there's
some benefit to a confederate to do the lens+forceps handling.
Got a glass splinter in my foot once, couldn't see it at ALL
and it stayed in a week before I even knew something needed
to be removed...
