Problem

Jupiter's magnetic dipole moment is about m=1.5×1027 A m2m = 1.5\times10^{27}\,\mathrm{A\,m^2}, and its field is generated in a conducting interior of radius about Rc=5.5×107 mR_c = 5.5\times10^7\,\mathrm{m}. Model that moment as produced by a single circular loop of current II at radius RcR_c, and estimate the current the loop would need to carry.
