Realistically the result wouldn't resemble these illustrations at all; a simple signal strength -> vibration intensity converter would be more practical.
What?
Doesn't seem all that useful from what i've read though, unless you're an electrical engineer.
I'd strongly encourage trying it. Been there done that. The glove thing, not the implant thing. Cheap and fun. You will "stick" yourself to chunks of steel and much simpler to fix that with a glove. It gets boring/annoying after a couple hours, at which point you're pretty happy to peel off the glove; I imagine implants are less convenient.
And its magnetic fields not electrical. Over a couple hundred volts/cm you can feel electrical fields without any implants or whatever, assuming you have arm hair. I'm talking about something distinct from feeling current flow, a totally different scenario.
You can feel CHANGING magnetic fields if they're immense, like in a MRI.
(Not questioning the implanted magnets; I just want to point out that one has to be careful when doing the non-implant version of this experiment with jumping to conclusions about what one feels.)
