B) solid iron core forming a permanent magnet.
C) liquid "metal" interior and relatively rapid rotation.
D) solid interior throughout the planet and slow rotation.

Question

Quizplus · Accepted Answer

The generation of a powerful magnetic field in a Jovian planet requires a liquid "metal" interior, such as metallic hydrogen in the case of Jupiter and Saturn, combined with relatively rapid rotation. This combination supports the dynamo theory, which explains how the motion of conducting materials can generate magnetic fields.
