A valuable lesson on magnetism

I have used one successfully.

I stuck a needle onto a rare earth magnet with Super glue. It made it MUCH easier to hold the needle while I dug the chip out. :-)

So pick up a surplus MRI machine, Ig.

One shouldn't be very hard for -you- to find.

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...

You should just leave it there, it'll (Trust Me!) give you A Magnetic Personality-

So, what is NOT powerless against chips stuck on foot? How stuck are the chips in the foot that you talking about in that personal observation? To give special mention to rare earth magnets, I can't really see the eye-opening revelation in your statement. :-)

I eat steaks for iron, chips are cheaper.

When I had an MRI, they asked if I worked with metal, grinding etc, they then took and xray of my eyes. Small metal particles go travelling in the MRI magnetic field and do nasty things to eyes. Maybe something to keep in mind!

Or just stay away from machining steel or iron. Or other magnetic metals. :-)

All seriousness aside, another thing to be aware of before getting an MRI is the presence of extensive tattoos. Some of the inks have enough iron in them that a magnet can be used to move a drop of the ink around on a piece wax paper. That can have some interesting (and painful) repercussions, especially if the patient has the "tribal" sort, where large patches are inked solid. I think the article mentioned heating of the ink enough to cause burns.
