The source of the magnetic fields in Uranus and Neptune is probably:
A)the flow of ionized solar wind particles around the planets in their magnetospheres.
B)the flow of impure water in deep layers of these planets.
C)the flow of liquid metallic hydrogen in the planets's interiors.

Question

Quizplus · Accepted Answer

The magnetic fields of Uranus and Neptune are thought to be generated by the flow of electrically conductive fluids (such as impure water) in deep layers of these planets, rather than by mechanisms such as solar wind interaction, liquid metallic hydrogen, or solid iron cores.
