In physics, polarity is an attribute with two possible values. Polarity is a basic feature of the universe.

An electric charge can have either positive or negative polarity.

A voltage or potential difference between two points of an electric circuit has a polarity, describing which of the two points has the higher electric potential.

A magnet has a polarity, in that it has two poles described as "north" and "south" pole.

More generally, the polarity of an electric or magnetic field can be viewed as the sign of the vectors describing the field.

The spin of an entity in quantum mechanics can have a polarity – parallel or anti-parallel to a given direction.
