biegun

Biegun is a Polish noun meaning pole or end of an axis, and by extension the opposite end or extremity of something. It is used in a variety of scientific and everyday contexts, and in compound forms to denote specific poles such as geographic or magnetic ones.

In geography, biegun refers to the poles of the Earth or other celestial bodies, most commonly the North Pole (biegun północny) and the South Pole (biegun południowy). The term can also denote a geographic pole more generally (biegun geograficzny). These poles are fixed in space relative to the body’s axis, though the Earth’s magnetic field has a separate, moving magnetic pole.

In magnetism, biegun magnetyczny denotes the two opposite poles of a magnet. Magnets have a north and a south pole, and magnetic interactions follow the rule that opposite poles attract while like poles repel. The concept is foundational in physics and various technologies, including compasses and electric machines.

Beyond physical meanings, biegun is used metaphorically to describe opposing sides or extremes in debates, politics, or culture, as in terms like bieguny polityczne or bieguny społeczne. The word is native to Polish and has cognates in other Slavic languages; its precise historical development is not detailed here.

In summary, biegun primarily designates poles or ends—geographic, magnetic, or metaphorical—and appears widely across science, geography, and discourse.
