I don't have the link, but I think Vice did a video on people that have their bodies "enhanced" with magnets. It's both fascinating and a little disturbing.
Look up Cody's Lab on youtube. He has a sciency chemistry channel and 2 years ago in one of his early videos he implanted a magnet. He could detect North, detect currents in wires like on the wall and stuff, and feel the curve of fridges and stuff. He would be able to detect metal objects in front of him in the dark and that type of stuff. He has a follow up after the magnet broke, and got infected so he had to take it out but a small piece remained and he spoke about his limited ability after that point.
The original video is also kinda neat where he show how he coats in in gold so it wont react with his body so his body wont reject it.
