The ferromagnetic material would have to be very close to the surface of the skin to hold even a very strong neodimium magnet because the field strength decreases according as the square of the distance.
I think mine is 50KG pull weight, so yea I thought it would stick even if very weakly. In the videos, though they seem to have a very precise sweet spot for attraction. For a huge magnet under the arm it would surely stick over a much wider coverage???
You think that if you put a magnet under your arm (armpit area) and then stick a magnet to your outer arm, it should stick? Dude ...

I can't say for certain, but I wouldn't think so. Perhaps someone with more magnet expertise could answer that question.
