Spherical multipole moments
text:
In physics, spherical multipole moments are the coefficients in a series expansion of a potential that varies inversely with the distance R to a source, i.e., as 1 R. Examples of such potentials are the electric potential, the magnetic potential and the gravitational potential. For clarity, we illustrate the expansion for a point charge, then generalize to an arbitrary charge density ρ. Through this article, the primed coordinates such as r ′ refer to the position of charge(s), whereas the u
