Hi all, I'm currently working on a game about magnetism and have run into some problems. I'm hoping that you guys here will be able to help me with it. I've been reading about magnetic phenomena on the net, and one of the things I've found is that the magnetic force exerted between two unlike poles is inversely proportional to the distance between them squared. If that's the case, then when two poles on a bar magnet are touching, shouldn't the force they are exerting on each other be infinite since x/0 = ∞? Also, another question I'm wondering about is this: if a strong magnet that is smaller in mass pulls a paramagnet towards itself with a vector V, does it experience an opposite vector -V? Or does it just experience the force that the induced pole on the paramagnet exerts on it? Thanks to anyone who might be able to help!
