Need help constructing a strong electric magnet.

[daveem Dave M]

I discovered that I have a small metal splinter in my finger, that has
gone so deep, I am not able to remove it with a conventional tweezers
and needle, unless I do some deep cutting, and I didn't even notice it,
until I had my finger near a permanent magnet yesterday, and felt
something deep beneath my skin trying to move around, so yesterday I
constructed an electric magnet, in the hope that I could extract it with
a strong magnetic field, but apparently it was not strong enough, and
while I understand the basics of electromagnetism, I am not sure how one
can build an electric magnet, that has a strong enough field to do the
job, other then passing as large a current as possible, through many
turns of wire that are wrapped around a metal core, and any help would
be very appreciated.
Thanks, Dave

Go get an MRI.

Use an extremely strong rare earth magnet instead. If it can't extract
the sliver then it's time to operate.

If the splinter is very tiny, which I suspect it is, its mass must be also
very small. It would also have to be made from a very high grade or pure
Ferris metal in order to have a good pull from a magnet.

If you have a magnet that is extremely strong near to your body parts, there
may be some adverse or questionable health issues. I am speaking of a very
powerful electromagnet, or permanent magnet. There are some speculations
about this.

Haven't you ever played with disk drive magnets? They are about the
most powerful easy to obtain magnets.
