Subdermal Magnets Allow You To Wear an IPod Like a Watch
Okian Warrior writes "Tattoo artist Jersey from Dynasty Tattoo (in New Jersey) implanted sub-dermal magnets in his arm to wear his iPod touch like a watch. From the article: '“Those magnets are actually called micro-dermal anchors, and in body piercing they are very common. The tops are actually just 5 millimetre magnetic tops,” he said. “I took the ends of magnets and actually adhered them to the back of the iPod, and that’s how they click into my skin.”
He added: “I can go for a run and it won’t come off. I’ve already taken it to the gym and jogged with it on.”'"
Seriously, there was a day and age when "magnets = bad" was the mantra. What kind of problems should this guy actually see with his gear, long term, subjecting it to strong magnetism? Will this mess with the memory in the device? Will this accelerate problems like tin whiskers?
Do not look into laser with remaining eye.
fingertip magents would be a very BAD idea.
the way it works is you have current whenever you have motion in a magnetic field so you would have all sorts of problems
(besides all you would need really is a small coil not a magnet)

It's pretty sweet. I've got one in my right thumb and index finger. I feel a buzz whenever there's a strong enough alternating field nearby, and a tug whenever I pass my hand near strong static magnets. I'll be walking down the street and feel sensors to detect the presence of cars, and I can feel the brakes in subway cars. Nothing particularly practical, but I figure I may get a couple of seconds warning before the shockwave if I ever feel an EMP.
In terms of strength, I can basically pick up staples. Anything heavier falls off. Other magnets I can drag around on the table pretty easily, though it's uncomfortable to have them actually contact my fingers.

Ah this old idea that pops up on /. every month or so.
This is where I relate that you can get ALMOST the same experience temporarily with stretchy gloves and little magnets in the fingertips. Obviously buy gloves with fabric fingers just a little longer than your fingers. In the frozen north, in season, this is not much of a challenge... Florida /.ers are probably all like, gloves, what are those?
It is fun for at least a couple hours. Try touching the body of a big motor or old fashioned xfrmr power supply. Variable speed AC/DC "universal" motors were not as much fun as I expected. Waving in front of a CRT screen is entertaining.
You want gloves thick/strong enough to not tear, but not so thick as to lose sensation.
GOOG for "magnetic wedding ring" and you'll find lots of crackpot "magnets cured mah arthritis" pure BS, but this is probably the ultimate in non-invasive experimentation. Unlike the Magnet-in-glove thing, I've not tried magnetic wedding rings.
The biggest problem with "magnets/hands" is what happens when it inevitably cracks. Sharp little ceramic shards pinching slashed up tissue. So don't go giving steel plates a "high five".

A week or two. Turn on a microwave--that should do it. Or go into a bookstore--you'll feel the scanners at the door.
I live in NYC, where there are all kinds of things hidden behind walls and under the sidewalk. Maybe you're just in an area deficient in weirdness?

I've had a magnet stuck to my head for about 15 years. It's called a cochlear implant. There's a metal plate embedded in my skull, but a moderately heavy-duty magnet holds the inductor coil in place. As far as I can tell, I haven't had any problems with this.
