Does the magnet even have to be implanted? I'd think that you could just stick it to your finger and get the same results without resorting to surgery. Perhaps just use one of those little rubber fingertips that administrative assistants use while filing?
This is my response to a previous comment in here, copy and pasted to you:
As someone with the actual implant, I'd say no.
Think of it this way, people have been wearing magnetic body jewelry as an alternative to piercings for decades. Sensing magnetic fields has never been associated with magnetic jewelry.
The same way that holding a buckyball between two fingers close to a fan doesn't really create an unusual or striking response, comparatively.
There's something unique about the implant that can't be replicated in other ways. I mean, I haven't tried this external device, but the above is my response to questions about magnetic rings, nail polish, earrings, etc.
What if it were glued on? The idea is cool, but there's no way I would want something surgically implanted like that. It's just better to be able to remove it when needed.
I say give it a try. It will be an experience, even if it's not the same experience.
I'd say a large part of the difference is mental. With an implant, your body internalizes the sensations, they're part of your body, your "one"-ness. With external sources, you may still feel the sensations, but they're not yours. Your body doesn't feel the fields, it feels an object that feels the fields.
I did that once. Taped a strong magnet to my finger. I could feel strong magnetic fields, but not for long as I had to keep it really tight. A neat experience though, no surgery required
