A powerful magnet, with only "pin point" accuracy would be real useful
for nail removal. In other words, the magnet would be held right over
the nail head. I'm not sure just how much force would be needed though.

VERY INTERESTING. Thanks for the link. I thought this was a possibility.
I'm surprised they are not being sold at every hardware store!

You didn't fall for that, did you? The fact that they aren't
being sold should tell you something. Anyone see even a prototype?

Exactly. You can patent just about anything. Being able to build it,
make it work, and withstand a patent challenge is another matter.
