Judging by previous instances, you ought to put in more than just a link and also put [LINK] in the title, or else you are liable to get a bunch of downvotes.
[edit] OK, watched the first video, with people getting little rare-earth magnets put in their fingers so they can feel magnetic fields... Why not just get a magnetic ring? That way you can feel magnetic fields and don't risk medical complications and you don't have to stop for several minutes and explain every time you fly or go through one of those scanners I hear are relatively common in the US. [/edit]
Not to mention your finger would fry if you'd ever find yourself in an MRI, though the implant might just as well burst out from your finger before you even lay down.
This was my main concern when thinking of getting one :(
I haven't had an implanted magnet, but I have had a (quite strong) magnetic ring, and I can tell you that the ring offers nowhere near the sensitivity of the implant. With the ring the most impressive thing I can detect is studs in a wall. My friends with implanted magnets can detect live wires.
The implant adds enough sensitivity to make you superhuman, in a way the ring definitely does not.
I thought that sensitivity might be the answer. Not that hearing fairly sensitive perception of magnetic fields is possible makes me want the ability enough to stick magnets in my fingers. Yet.
I've heard about other superhuman sensory devices, like the compass-sense belt, though, and the more I hear about this stuff, the cooler it sounds. Perhaps sometime the rising interest and falling cost/inconvenience curves will cross for me. :)
Security things don't detect them.
I can see X-ray or terahertz scanners missing a tiny lump of metal, but aren't there a fair number of magnetic scanners in use looking for larger lumps of metal, which I'd think the magnet would interact fairly strongly with?
I don't know about that, but I've been through multiple security checkpoints since getting them and they've never been noticed.
But can you handle HDDs, without risking data corruption?
I've never had a problem. I have an iphone and it's never gotten corrupted, and thumb drives are always fine. I haven't tried rubbing my fingers all over one of the disk drives in my computer though
I see, while we are at, how do you precive magnetic fields? e.g. stretching of the skin. I assume the magnet is located between your skin and your fingers fat pad. I'm wondering since Bakkot reports that rings seems to be a lot less sensitive, I want to know what makes putting it under the skin any diffident.
it mainly feels like a buzzing. It's right up against then never that goes into your fingertip.
Exclaimer: feel free to ignore my questions.
Interesting, do you know if that is from the push/pull from the magnet on your nerve or if it is a current generated as you move your finger in a magnetic field or something?
I think it's probably the first one. Generated fields feel like buzzing and permanent magnets just feel like a pull, so I think the "buzz" is an effect of the field moving.
Credit to Bakkot for having tried out and reported on magnetic rings, not me.
Wouups - FIXED - thanks for pointing that out!
