  Jupiter's internal flow structure is still not fully known, but can be now
better constrained due to Juno's high-precision measurements. The recently
published gravity and magnetic field measurements have led to new information
regarding the planet and its internal flows, and future magnetic measurements
will allow taking another step in resolving this puzzle. In this study, we
propose a new method to better constrain Jupiter's internal flow field using
the Juno gravity measurements combined with the expected measurements of
magnetic secular variation. Based on a combination of hydrodynamical and
magnetic field considerations we show that an optimized vertical profile of the
zonal flows that fits both measurements can be obtained. Incorporating the
magnetic field effects on the flow better constraints the flow decay profile.
This will allow getting closer to answering the long-lived question regarding
the depth and nature of the flows on Jupiter.
