I was having some trouble understanding how an electric dipole creates an electric field around it? Shouldn't the two oppositely charged particles in the dipole totally cancel out their electric fields? Well, I figured out that the two particles only exert a force on eachother, but they cannot cancel out their fields. Because, physically speaking, an electric field spreads out in all directions around the particle, and it exists as long as the particle, which is charged, exists. And, the presence of the oppositely charged particles for eachother do not remove the other particles existence, and hence it's electric field? But, if that is so, then how does an atom, or the vast number of molecules around us not create an electric field around themself. Do the sub-atomic particles in the atoms and molecules cancel out eachother's electric fields?
