magnetic pole in Science
magnetic pole  
  1. Either of two regions of a magnet, designated north and south, where the magnetic field is strongest. Electromagnetic interactions cause the north poles of magnets to be attracted to the south poles of other magnets, and conversely. The north pole of a magnet is the pole out of which magnetic lines of force point, while the south pole is the pole into which they point. The Earth's geomagnetic "north" and "south" poles are, in fact, magnetically the opposite of what their names suggest; this is why the north end of a compass needle is attracted to the geomagnetic "north" pole. See Note at magnetism, See also monopole.

  2. Either of two regions of the Earth's surface at which magnetic lines of force are perpendicular to the Earth's surface. The Earth's magnetic poles are close to, but not identical with, both its geographic poles (the North and South Poles) and its geomagnetic poles. See Note at magnetic reversal.

magnetic pole definition

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.”
