WebMultipole expansion of the magnetic vector potential Consider an arbitrary loop that carries a current I. Its vector potential at point r is Just as we did for V, we can expand in a power series and use the series as an approximation scheme: (see lecture notes for 21 October 2002 for derivation). I r =−rr′ r r’ θ dA ()= v∫. Id c Ar A r ...
