The existence of a liquid, [[iron–nickel alloy|iron–nickel]]-rich core<ref name="Bhatia2017" /> provides a natural explanation for the intrinsic [[magnetosphere|magnetic field]] of Ganymede detected by ''Galileo'' spacecraft.<ref name="Hauk2006">{{cite journal |last1=Hauck |first1=Steven A. |last2=Aurnou |first2=Jonathan M. |last3=Dombard |first3=Andrew J. |title=Sulfur's impact on core evolution and magnetic field generation on Ganymede |journal=J.
