magnetic pole

American  

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.

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 Scientific  

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.

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

Pulsars emit powerful beams of electromagnetic radiation from their magnetic poles at intervals measured in milliseconds.

From Science Daily

According to Nasa, it comes roughly every 11 years when the Sun's magnetic poles flip - the Earth equivalent would be the North and South poles swapping positions.

From BBC

The Sun's magnetic cycle is a repeating pattern that lasts about 11 years, marked by fluctuations in sunspot numbers and a complete reversal of the Sun's magnetic poles.

From Science Daily

Aurora displays are caused by charged particles from the Sun colliding with gases in the Earth's atmosphere around the magnetic poles.

From BBC

The increase in eruptions is brought about by the Sun's magnetic poles flipping.
