Why is Saturn's magnetic field 20 times weaker than Jupiter's?
A) The decreased pressure on Saturn implies a smaller liquid hydrogen layer.
B) Saturn's atmosphere responds easily to magnetic fields, partially canceling them.
C) Saturn's rapid rotation causes its electric currents to short-circuit.
D) All of the above.

Quizplus · Accepted Answer

Saturn's magnetic field is weaker than Jupiter's primarily because the decreased pressure on Saturn results in a smaller liquid hydrogen layer, which is crucial for generating the planet's magnetic field. The magnetic field is generated by the movement of conducting materials (such as liquid hydrogen) inside the planet, and a smaller layer means less material to generate a strong magnetic field.
