James, the global effect is independent from polarity. When the wire is positively charged, the negative end of the dipole is attracted and will be directed closer to the wire, the positive is repulsed, is further away. During the negative cycle of the wire, the whole thing is reversed. During both polarities of the wire the dipoles are attracted (because of the different distances of the dipole charges to the wire), but the dipoles change permanently their directions. Because attraction and repulsion both take place simultaneously, the force on a dipole in an unhomogeneous field is weaker as on a singular charge (e.g. an ion). you see, the dipole is permanently oscillating or rotating in an alternating electrical field. If there is also a magnetic field, as it is around an electric current, there are also forces transverse to that field, which makes the movement more complicated.
