The electrostatic potential at position r due to an electric dipole at the origin is given by: where p is the (vector) dipole moment, and є0 is the permittivity of free space. This term appears as the second term in the multipole expansion of an arbitrary electrostatic potential Φ(r). If the source of Φ(r) is a dipole, as it is assumed here, this term is the only non-vanishing term in the multipole expansion of Φ(r). The electric field from a dipole can be found fr… WebA dipole is a separation of opposite electrical charges and it is quantified by an electric dipole moment.

Web3.1. Electric dipole Let us consider a localized system of charges, of a linear scale a, and derive a simple approximate expression for the electrostatic field induced by the system at a distant point r. For that, let us select a reference frame with the origin either somewhere inside the system, or at a distance of the order of a from it (Fig. 1).
