Pólusú

Pólusú is a Hungarian adjective meaning having poles or being polar. It is used to describe systems or objects that exhibit polarity, typically characterized by two ends with different properties, such as opposite electrical or magnetic charges, or a separation of charge in a molecule.

The term derives from pólus, meaning pole, and is used across several scientific contexts. In chemistry, a pódusú molekula (or poláris/molekula) refers to a molecule with an uneven distribution of electron density, producing a positive and a negative end. Common examples are water (H2O) and ammonia (NH3). In contrast, apoláris molecules, like hexane, lack such a distinct charge separation. In physics and magnetism, a pólusú magnet or a pólusú rendszer describes objects with distinct magnetic poles, such as north and south.

In practice, pólusú is often used interchangeably with poláris, especially in older or more general Hungarian texts. It appears in scientific writing, teaching, and glossaries to convey the idea of polarity without invoking more technical terminology. The concept underlies related terms such as dipólus, polarity, and dipole moment, which describe the degree and direction of separation of charges.
