Hello everyone, I would like to ask a couple of questions which are related to electric dipole moment and electric field. First one: Let us assume that we have somehow a constant electric field. The obvious thing to say is that any material that contains a Net Charge ( moving one or not moving one) will be affected by this electric field. My question is, is a net charge enough for something, in order to be affected by an external electric field? In a case that something has zero net charge, but DOES have an electric dipole moment, will ''something'' be affected by this electric field inspite of having zero net charge, just because it has a non zero electric dipole moment? Second one: In the case that we have a molecule of water which if I am not wrong, DOES have a non zero electric dipole moment, but a zero net charge, which will the result be if we apply an external electric field? A dc current carrying wire since being neutral will not attract or deflect an external charge right? Does it mean that its electric dipole moment is zero? Third one: Is electric dipole moment connected with electric field somehow? For example can we have something that has zero net charge and non zero electric dipole moment? Or something that does have a net charge but at the same time zero electric dipole moment? Or is it true to say that something that has electric dipole moment, creates ath the same time its own electric field? Fourth one: Does question number four have something similar in magnetism? And finally is it true to say that a neutral atom that has only s electrons, due to spherical symmetry, will have zero electric dipole moment since it is not an electric dipole and thus the centers of positive and negative charges are at the same place? Thanks a lot for your time. Hope that my questions are clear.
