biegunów

Biegunów to genitive plural form of the Polish noun biegun. The noun biegun denotes a pole or end of something and is used in multiple domains to refer to physical poles as well as abstract extremes. In science and geography, the main senses are magnetic poles and geographic poles.

Magnetic poles: A magnet has two ends that act as magnetic poles. Earth’s magnetic field defines a magnetic North Pole and a magnetic South Pole, which wander over time as the core dynamics cause changes in the field.

Geographic poles: The Earth’s geographic poles mark the points where its axis of rotation intersects the surface: the North Pole in the Arctic Ocean and the South Pole on the continent of Antarctica. The geographic poles are fixed in a rough sense, but their exact position is defined by convention and can be updated with measurements. The geomagnetic field is separate from the geographic axis and can drift and even reverse.

Usage: The form biegunów appears in genitive plural; used after prepositions that require genitive or in constructions where the poles are described or possessed, e.g., od biegunów magnetycznych, z biegunów geograficznych.

Etymology: The term derives from older Polish, used to denote endpoints or extremities; the word forms with genitive plural as biegunów. The distinction between geographic and magnetic poles is common in geography and physics, and the plural form biegunów is routinely used when referring to multiple poles in these contexts.
