Alternative implantation locations
Does anyone have any experience with implanting magnets in any place other than the fingertips? I'm curious what other body parts (and no, I'm not going to get amateur surgery done to the other obvious location) have the requisite nerve density for the magnets to work properly. I'm not so much concerned with being able to 'feel' AC fields from several feet away (although that would be cool, and I may get other ones in my fingertips for that purpose), as much as being able to feel the field of a flat spiral electromagnet that's pushed up against my skin (depending where on my body the magnet ends up, I'm thinking a maximum of about 2 inches OD for the coil, so not that strong of a field).
I apologize if I'm stealing Grindhouse Wetware's thunder; your post gave me the idea for this :)
As for using genitals, I had an idea a while back that maybe implanting magnets in your's/your lover's lips and/or genitals would increase sensation. It's batshit crazy, I know, but it's also interesting.
EDIT: Don't worry about stealing our thunder, by the way; this forum was made to have stuff discussed on it. Also, as has been noted, static fields can't be picked up by the magnets. An active EM sensor, as has been proposed before, would be able to pick up fields much better than the passively-sensing magnets could, but the only way I can think of to pick up static fields would be a Hall-effect sensor.
If I am correct (1 in 20 chance) an induction coil produces a current when moved within static fields. This current has some advantages over the regular buzzing of a standard magnet. I'd like to do some experiments with these to see just how sensitive/painful voltage is when applied near a nerve. Also, I'm curious to see if I can force any synesthesia from the sensation. The magnet in my finger already gives me a faint sensation of texture, but that seems to go away quickly because the buzzing kind of numbs the finger. Not sure if others are experiencing this.
Does anyone have a sensitive piercing they want to try it on? I'll see if I can get an induction coil today and attach it near a nerve somewhere.
Why am I not surprised?
Anyhow, I clipped an end in each nostril so that it surrounded a nerve that I know of. When I passed the magnet by the coil I definitely felt a "warm" sensation in my nose, followed by a change in sinus pressure. The sensation in my sinuses seemed to move with the magnet so I could tell approximately where the magnet was in relation to the coil. I'm not sure what is occurring here but it is definitely worth looking into. I'm not even pulling a voltage here so this shouldn't be happening, right?
induced voltages are very small (unless you have a very fast changing field). for most small coils you'd need frequencies in the khz region to be able to messure anything with a small handheld multimeter.
i am a bit surprised about your nose experience tho. it takes me almost 5 volt over a very small distance (between clips) to cause enough current to flow to be noticeable at all.
