Polarity \Po*lar"i*ty\, n. [Cf. F. polarit['e].]
(Physics) That quality or condition of a body in virtue of which it exhibits opposite, or contrasted, properties or powers, in opposite, or contrasted, parts or directions; or a condition giving rise to a contrast of properties corresponding to a contrast of positions, as, for example, attraction and repulsion in the opposite parts of a magnet, the dissimilar phenomena corresponding to the different sides of a polarized ray of light, etc.
(Geom.) A property of the conic sections by virtue of which a given point determines a corresponding right line and a given right line determines a corresponding point. See Polar, n.

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.

Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes four types of systems: unipolarity, bipolarity, tripolarity, and multipolarity for four or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
It is widely believed amongst theorists in international relations that the post-Cold War international system is unipolar: The United States’ defense spending is “close to half of global military expenditures; a blue-water navy superior to all others combined; a chance at a powerful nuclear first strike over its erstwhile foe, Russia; a defense research and development budget that is 80 percent of the total defense expenditures of its most obvious future competitor, China; and unmatched global power-projection capabilities.”
Polarity is a board game that requires strategic thinking and dexterity to control hovering magnetic discs. Polarity was invented in 1985 by Canadian artist and designer Douglas Seaton. It was first published in 1986. The game has had a tumultuous past, with its rights changing hands several times over the past 2 decades. The game has been published by Telemotion Technologies, Irwin Toy, briefly with Mattel and most recently by Temple Games. The game ships in a canvas sleeve and include the magnets, the board, and a paper rulebook. An unrelated game of the same name is published by a company called Mindwalk (Company).
The purpose of the game is to gain points by forming towers of discs. The playing pieces are magnetic discs, with one side white and the other black, north and south respectively. They are identical with the exception of a neutral central disc which is coloured red.
Play starts with one player tossing the central red disc in order to determine which player plays with which colour/magnetic polarity. Each player then lays 5 'foundation discs' of their colour starting with the white player. Each disc can be placed on the playing area with no limitation other than to be inside the external circle and not touching the red disc.
Play then proceeds by placing further discs within the playing area, balanced, leaning, on the magnetic fields of preceding pieces. These pieces are known as 'leaners'. Moves which disrupt the pieces currently in play by making them fall or stick together are known as 'faults', and end a player's turn. If a fault results in two or more pieces touching each other, the opposing player then has an opportunity to capture those pieces by forming them into towers, which at the end of the game score points. Occasionally a player will intentionally fault, causing one of their own pieces to fall flat onto the play surface, thus making it easier to play further pieces.
The play ends when one player has exhausted their supply of pieces or if a piece touches the center red disc. The winner of the game is determined by points scored, which are based on the number of pieces in towers of a player's color, and the pieces remaining in the opponent's hand.
The polarity of a device with mutual inductance designates the relative instantaneous current directions of such device's winding leads.
A dot marking convention, or alphanumeric marking convention, or both, can be used to denote the same relative instantaneous polarity of two mutually inductive components such as between transformer windings. These markings may be found on transformer cases beside terminals, winding leads, nameplates, schematic and wiring diagrams.
Leads of primary and secondary windings are said be of the same polarity when instantaneous current entering the primary winding lead results in instantaneous current leaving the secondary winding lead as though the two leads were a continuous circuit. In the case of two windings wound around the same core in parallel, for example, the polarity will be the same on the same ends: A sudden (instantaneous) current in the first coil will induce a voltage opposing the sudden increase ( Lenz's law) in the first and also in the second coil, because the inductive magnetic field produced by the current in the first coil traverses the two coils in the same manner. The second coil will therefore show an induced current opposite in direction to the inducing current in the first coil. Both leads behave like a continuous circuit, one current entering into the first lead and another current leaving the second lead.
Polarity is the second release from American punk rock band, The Wedding. Polarity was released on April 17, 2007. The new album showed a drastic change, vocally and musically, from the band's debut album. Polarity features guest appearances by Davy Baysinger from Bleach, duet vocals; Dan Spencer Supertones with a trumpet line; and Josh Robieson (Flatfoot 56), bagpipe riff. This is the last album to include Lead Vocalist/Pianist Kevin Kiehn.
"Say Your Prayers" is the first single from the record. It was released to radio airwaves February 17, 2007. In the first week of release, "Say Your Prayers" tied for the number 1 spot in radio station adds on Radio and Records national Christian Rock charts (February 23, 2007). Within the second week, the song hit the top 30 (March 2, 2007). On March 30, 2007, it entered the ranks of the top 10.
The band gave away a free song, "It's Time To Rock, OK?", off the album through the website My Free Music Friday.
