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

The terrestrial planets generate magnetospheres within the iron cores at the center. This leads to dipole-shaped, rounded magnetic fields. However, Uranus has almost no iron core.

The magnetic material of Uranus is found within the icy shells found within Uranus. Motions within those shells produce the magnetic field.

The Earth-like planets generate magnetospheres within the iron cores at the center. However, Uranus has almost no iron core.

The magnetic material of Uranus is found within the icy shells inside Uranus. Motions within those shells produce the magnetic field.
