What conditions are considered to be necessary for a planet to be able to generate an intense magnetic field?
A) ionized and electrically conducting layer in its atmosphere
B) electrically conducting material in its interior and slow rotation because rapid rotation will destroy a magnetic field
C) solid iron core into which a magnetic field was induced early in the planet's history
D) relatively rapid rotation and electrically conducting material in its interior

Question

Quizplus · Accepted Answer

The generation of an intense magnetic field in a planet typically requires the presence of electrically conducting material in its interior, such as a liquid iron core, and relatively rapid rotation. These conditions facilitate the dynamo effect, where the movement of conducting material generates a magnetic field.
