The shape of Earth's magnetic field is approximately that of a ____________.
A) monopole
B) dipole (such as that produced by a bar magnet)
C) torus, a donut-shaped ring parallel to Earth's equator

Question

Quizplus · Accepted Answer

Earth's magnetic field is best described as a dipole, similar to that produced by a bar magnet. This means that it has a north and south magnetic pole, and the magnetic field lines extend out from the north pole and curve back around to the south pole. While there are additional complexities to the field, such as non-uniformities and variations, the overall shape is most accurately described as a dipole.
