WebMultipole expansions are used frequently in the study of electromagnetic and gravitational fields, where the fields at distant points are given in terms of sources in a small region. The multipole expansion with angles is often combined with an expansion in radius. WebMultipoles are usually thought of as coe cients in an asymptotic radial expansion of a eld. This makes it a tricky business to de ne gravitational multipoles in general relativity due to general coordinate invariance. Nevertheless, Geroch [1] and Hansen [2] managed to de ne and calculate gravitational multipoles of stationary, asymptotically scrubby crochet yarnWebA simple way to envision what the higher-order multipoles “look like” is to construct them from the lower-order ones: take two of the lower-order ones, invert one, and place the two in close proximity. The monopole moment (charge) is a scalar. The dipole moment is a vector. Higher order multipole moments are scrubby daddy holder
