I'm going to do something. I NEED TO know if it's safe

  1. Jan 21, 2006 #1
    first off you need to know two things. 1. I just bought some super strong neodymium magnets. They are super small, shaped like rounded corner cubes about 3mm wide. The second thing you need to know is I do a lot of magic tricks.
    If I swallow one of these magnets I think the possibilities for neat magic tricks are obvious. but I want to know if I'm going to die if I do. There are no sharp edges to worry about and I'm sure I can pass one through my system.
    gimme some feedback

    Stay far, far away from thumbtacks, paperclips, pushpins, um... I suppose your computer too, but for different reasons!

    they are smaller than a peanut and don't have as sharp of edges

    Hahaha!

    The acids in your stomach will attack the protective coating on the magnets, they wont be pretty when/if they come out [for more than one reason].

    Why not just OD on iron pills and die? :)

    I doubt that swallowing magnets is safe...

    yeah I was wondering about that. is neodymium toxic?

    Even if you do swallow it, the magnet will not nearly be powerful enough to feel the effects outside your body.

    I think I can affect a compass from that distance. and I also think I could get it to hold up another magnet on my outside. but then I run the pinch risk.

    Brittle, sintered, sharp fracture edges, possibly close enough to the abdominal surface to be strongly attracted to your belt buckle? Dunno if I'd recommend it --- the chances of performing the first, live, no-hands appendectomy aren't all that large, but still ....

    If you can get a good mm or two of high density polyethylene coating to hold the things together, it might be safer. However, the m.p. of the polyethylene is gonna be higher than what the magnets take without losing their magnetism, so that's gonna be tough.

    i think it sounds like a great idea. get video of all your neat tricks. see how far you can let it go down your throat and use the other magnet to suck it up.

    I cant find many good MSDS sheets about neodymium, but NdCl3 doesnt look to good, and the Iron in the magnets reacting with the HCl in your stomach definatly isnt too good.

    You're right Gale, that is for more than one magnet. Alright then, go for it trib :smile:

    Actually, the magnetic field won't be strong enough to do anything but affect the compass. He can't hold a magnet up on his belly or anything.

    Cows will be given magnets to attract any hardware (nails, etc.) that they may have ingested. However, I doubt they are ever given more than one at a time. If I'm not mistaken, they often stay in the stomach.
