|1.||either of two regions in a magnet where the magnetic induction is concentrated|
|2.||either of two variable points on the earth's surface towards which a magnetic needle points, where the lines of force of the earth's magnetic field are vertical|
|1.||the northernmost point on the earth's axis, at a latitude of 90°N|
|2.||astronomy Also called: north celestial pole the point of intersection of the earth's extended axis and the northern half of the celestial sphere, lying about 1° from Polaris|
|3.||(usually not capitals) the pole of a freely suspended magnet, which is attracted to the earth's magnetic North Pole|
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.”
