Which of the following is NOT a requirement for a planetary magnetic dynamo?
A) rapid rotation
B) solid iron core
C) convective motions
D) charged particles in the interior
E) liquid interior

Question

Quizplus · Accepted Answer

A solid iron core cannot undergo convective motions, which are necessary for the generation of a planetary magnetic dynamo. Therefore, a requirement for a planetary magnetic dynamo is a liquid interior. Rapid rotation, convective motions, charged particles in the interior, and a liquid interior are all necessary for the generation of a planetary magnetic dynamo.
