AB - <jats:p>Permanently magnetic Ganymede carves a distinct magnetosphere insideJupiter’s larger magnetic domain, confined by ambient Jovian plasma andmagnetic field along the upstream magnetopause. As Ganymede traversesthe Jovian plasma sheet, ambient magnetoplasma conditions vary athalf-synodic period (5.27 hr), leading to same-period oscillation in theChapman-Ferraro (C-F) magnetic field produced by the magnetopause. Weassess the C-F magnetic field as a unique excitation source forGanymede’s subsurface ocean. The magnetopause field is shown to diffuseinto but not through the ocean, causing magnetic induction provided theliquid layer thickness is >~30 km. Thenusing an analytical model, we calculate maximum variation of the C-Ffield and estimate ~1-10 nT inductive response from theocean subjected to the magnetopause’s movement, a range detectable bythe JUpiter ICy moon Explorer (JUICE) spacecraft. Hence, Ganymede’smagnetopause may become a viable tool for future induction-based studyof the moon’s subsurface ocean.</jats:p>
