Getting metal out of my eye with electromagnet.

Getting metal out of my eye with electromagnet.

(OP)
I was doing some metal fabrication when a grain of sand sized piece of iron shot into my eye. It is barely deep enough to be stuck, It still scrapes the inside of my eye lid when I blink. I know it can be pulled out with a magnet, so I am making one that has a small dense flux.
●I already made a regular diy microwave electromagnet.
●Went a step further and used a permanent magnet the size of a deck of cards as the electromagnetic core. It even has two pieces of steel on eather side of it for directing the flux to one edge of the magnet.
●Went even further and hooked up 3 car batteries instead of one. 36 volts. I even put the magnet in the freezer beforehand for stronger magnetism.

It easily lifts brake drums, however a grain of sand sized piece of iron has less magnetic pull than a larger piece of iron.

So how do I direct the magnetic flux into a small dense point/area?
What is the best electromagnetic core shape for high flux density?
Should I keep adding power?

RE: Getting metal out of my eye with electromagnet.

!!! I commend your efforts, self-starting and general can-do gun ho attitude but it would probably go better in a zombie apocalyptic world than a modern world where you should just go to an eye doctor where they can carefully remove the the fleck under high magnification and check carefully for any tidbits being left in your eye. You are on the cusp of disaster. All sorts of ramifications can arise from metal in your eye that can cause long term issues. An eye doctor will provide you with the required eye drops needed to prevent any one of a dozen possible infections that could render your eye permanently useless.

Furthermore consider you have a metal shard or sliver in you eye. You show up with your magnet and with it in a slightly wrong angle it drags the shard thru more of your eye on the way out. That'd suck.

I've had metal removed from my eye, it's often the first thing they go for as it's very straight forward. It was the non-magnetic granite chip that was the biggest hassle.

The thing is that I have very little money. I would go to the doctor otherwise. These are my options, pull it out with an electromagnet or with a needle on my own. I am choosing magnet if someone can tip me on building one with a dense flux point.
The fragment of metal will come out clean with a magnet, like I said, it is barely stuck, like a stuffed animal hanging on the edge of a crane machine.

Then just get a magnet out of a discarded hard disk drive. Do not screw with electromagnets that could explode next to your eye.. The magnets in HDDs are EXTREMELY powerful and small. They are rare earth magnets.

I appreciate that advice, unfortunately I have tried those as well. The key is high power condensed into a dense flux point. Something to use for picking up something small with low magnetism.

RE: Getting metal out of my eye with electromagnet.

I think the following are the only two viable magnetic approaches
> take a harddrive magnet and use a Phillips screwdriver tip as the magnetic probe. The magnet will increase the strength of whatever magnetism the screwdriver has by at least a factor of 5.
> use the Phillips screwdriver shank to wind as much magnet wire as you can get on it to make your electromagnet

Alternately, get a set of sharp tweezers and find someone with steady hands

RE: Getting metal out of my eye with electromagnet.

Hey guys,
I wanted to update this post and let everyone know I am okay! One moon cycle after I made this post, my eye "pooped" out the piece of iron on it's own.
My vision got blurry and I had immense headaches. My eye made this milky substance surrounding the piece of iron and then magically, I woke up in the morning and it was gone. Vision was still blurry for 2 days after but it is back to normal now. The milky color was there for a bit too, however my eye is now back to it's hayzel original color.
Thanks to everyone that tried to help out, I gave up on the electromagnet and kept faith that my body would do something about it. Also I realised the electromagnet I would have to build would be extremely expensive in my perception.
Up next I have a filling I want to remove, this time I could use a helping hand because it's in a hard to see place. I am youtubing dentistry videos and it seems a dremmel will do the job. Lot's to learn, thanks all!

RE: Getting metal out of my eye with electromagnet.

Great! I have been wondering how your eye is. Use goggles in the future. I do from now on.
BTW, my Dremel is helping me with much more than grinding. And the filings are less dangerous and do not set things afire.
