Question

The earth's magnetic field appears as if it were produced by a strong permanent magnet embedded in its core. In the figures below, the earth is shown with the northern hemisphere on top, its core magnet is illustrated by the overlayed bar magnet, and a compass is illustrated as a diamond with a black tip at its magnetic north end. Which figure has the core magnet and compass magnet in roughly the proper orientation?

Answer 1

The north pole of a compass needle is a magnetic north pole. It is attracted to the geographic North Pole, which is a magnetic south pole (opposite magnetic poles attract).
Therefore, 3 is the correct choice.
