Multipole expansion of scalar potential
WebAnswer (1 of 2): A2A. As Quora User says, a Multipole expansion is about reproducing some given vector potential (or other vector field) as a sum of Spherical harmonic functions. Spherical harmonic functions are just a set of Orthogonal functions which have simple forms in spherical coordinates, ... Webscalars (for the scalar potential) or vectors (for the vector potential or field strength) with the irreducible tensors specifying the corresponding fields (called the multipole fields [1]). The expression for multipole expansion in electrostatics can be found in any textbook on classical electrodynamics (see, e.g., [2]).

Webthat is, the scalar potential satisfies the Laplace equation at the expansion point. In the static case, electric multipoles are often redefined to give forms that are traceless on any two indices. In this manner, the above restrictions (154) can be incorporated [ 49 ]. The general form of such traceless multipole operators is [ 73 ] Webthe standard Newtonian potential plus a term stemming from massive scalar fields. General solutions have been found for axisymmetric systems and the multipole expansion of the Yukawa potential is given. In parti-cular, we have computed potential–density pairs of galactic disks for an exponential profile and their rotation curves.
WebA multipole expansion is a mathematical series representing a function that depends on angles—usually the two angles on a sphere. These series are useful because they … Webpotential and multipole expansion of the magnetic vec- tor potential inside a sphere of radius R is obtained. 1.
