I read about people getting magnets implanted so that they can feel magnetic/electrical fields
Not quite ready to commit to implants, but i did try gluing some tiny magnets to my fingernails once.
I suspect that the implants are a bit more sensitive since they can kind of wiggle around under your skin more, but I could definitely feel some things, the two that stuck out to me were a forklift charger and an electric pencil sharpener.
I also got really used to picking up paperclips and other small metal things like that with them. I only had the magnets for maybe about a week, but I caught myself still trying to pick up paperclips with them for probably about a month afterwards.
Luckily most people with those sorts of implants I’ve seen are fairly scientifically-minded, and I’d like to think that’s the sort of thing they’d think of and would wear some sort of appropriate medic alert bracelet.
It’s not like there aren’t other sorts of medical implants, piercings, situations like people with shrapnel embedded in their bodies, etc. out in the world that could potentially cause issues with an MRI machine.
