Hi! I was wondering how I would go about solving a problem like this: (I have experience with up to multi-variable calculus and moderate level physics) So I'm trying to see if it's plausible to create electromagnets, which fit into gloves and/or boots, that would allow a person to climb around a metal building like a bug. I'm assuming your entire system (body and gear) weighs 100 kg for the sake of this problem. I've managed to figure out that to stay connected to the building you'll need the magnet to apply a force of about 6533.3 N to the building you're on. My question is, how do I calculate, under reasonable assumptions made about the design of such items (fits in the hand, no area as large as 10 m^2 for example) the electrical requirements for such a feat (voltages, current, etc.) Thank you!
