Need help constructing a strong electric magnet.

  1. 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.

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