The Making of Uranus' Magnetosphere
Magnetosphere's are generated with 1.) magnetic materials and 2.) with motions within the magnetic material.
The Earth-like planets generate magnetospheres within the iron cores at the center. Uranus has almost no iron core, however.
The magnetic material of Uranus is found within the icy shell found within Uranus. Motions within that shell produce the magnetic field.
