The Generation of Saturn's Magnetosphere

Magnetospheres are generated with 1.) magnetic materials and 2.) with motions within the magnetic material.

The Earth-like planets generate magnetospheres from iron at the center.

But Saturn has almost no iron core. The magnetic material of Saturn is found within the liquid metallic shell. Motions within that shell produce the magnetic field.
