(In this context, “close” means that the distance d between the two charges is much, much less than the distance of the field point P, the location where you are calculating the field.) Let’s now consider what happens to a dipole when it is placed in an external field E → E →. Explain the physical meaning of the dipole momentĮarlier we discussed, and calculated, the electric field of a dipole: two equal and opposite charges that are “close” to each other.Define and calculate an electric dipole moment.By the end of this section, you will be able to:
