Why would an electrostatic force repel humans? We are neutrally charged.
And if anything, in metals I think (???) you can get attraction as free electrons in the neutral body are attracted/repelled towards the charge and the neutral body becomes a dipol (so eg. if the charged body is positively charged then the negatively charged electrons are attracted towards it, and vice versa). But that's weak and acts the wrong way.
- dcminter 2y agoI suppose you could take advantage of diamagnetism if a moving charge was involved... it works for frogs :)
- danparsonson 2y agoIt's possible to induce charge in things - this principle is used for holding silicon wafers inside lithography machines but works for other materials too (https://youtu.be/pgV8l5yLadQ https://youtu.be/pgV8l5yLadQ)
- dcminter 2y agoOr on the other side you remind me of a literal party trick - a rubber balloon filled with helium that's starting to deflate and thus has neutral buoyancy can be moved around without touching it. The charges on the surface of the balloon and on your hands repel.
