|
The northern end, or pole, of the Earth's axis. (See Arctic and Arctic Ocean.)
The spot on the Earth toward which a compass needle will point.
Note: The north magnetic pole is not located exactly at the geographic North Pole. Therefore, depending on where a compass is, its needle may not point exactly north.
Note: The variation between magnetic north and “true” north is usually shown on navigation maps as the “angle of declination.”
