magnetic pole

noun

1. the region of a magnet toward which the lines of magnetic induction converge south pole or from which the lines of induction diverge north pole.
2. either of the two points on the earth's surface where the dipping needle of a compass stands vertical, one in the Arctic, the other in the Antarctic.

magnetic pole

noun

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

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.

3. 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 .
4. See Note at magnetic reversal

magnetic pole

1. The spot on the Earth toward which a compass needle will point.

Notes

The variation between magnetic north and “true” north is usually shown on navigation maps as the “angle of declination.”

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.

Example Sentences

Aurora displays occur when charged particles collide with gases in the Earth's atmosphere around the magnetic poles.

From BBC

Aurora displays occur when charged particles collide with gases in the Earth’s atmosphere around the magnetic poles.

From BBC

They also found that these changes were synchronised with changes in the white dwarf's magnetic field, indicating that this metal scar is located on one of its magnetic poles.

From Science Daily

This is distinct from the northernmost magnetic pole, which is the point where Earth's magnetic field points vertically downward, although the two locations are relatively close to each other.

From Salon

The northern lights appear in a region around the earth’s magnetic pole, called the “auroral oval” or “auroral zone”, explains Don Hampton, research associate professor at the Geophysical Institute of the University of Alaska Fairbanks.
