  The last 22.5 orbits of the Cassini mission brought the spacecraft to less
than 3000 km from Saturn's 1-bar surface. These close encounters offered an
unprecedented view of Saturn's magnetic field, including contributions from the
internal dynamo, the ionosphere, and the magnetosphere. In this chapter, we
highlight the new picture of Saturn's magnetic field from the Cassini mission
including the persistent yet time-varying low-latitude field-aligned currents,
Alfv\'en waves planet-ward of the D-ring, extreme axisymmetry, and high-degree
magnetic moments. We then discuss the implications and new questions raised for
Saturn's innermost magnetosphere, equatorial ionosphere, and interior. We
conclude this chapter with an outlook for the future exploration of Saturn and
other giant planets.
