Polarity :: Polarity (n.) 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..

Pyroelectric :: Pyroelectric (a.) Pertaining to, or dependent on, pyroelectricity; receiving electric polarity when heated..

Pole :: Pole (n.) See Polarity, and Polar, n..

Inherent :: Inherent (a.) Permanently existing in something; inseparably attached or connected; naturally pertaining to; innate; inalienable; as, polarity is an inherent quality of the magnet; the inherent right of men to life, liberty, and protection..

Electricity :: Electricity (n.) A power in nature, a manifestation of energy, exhibiting itself when in disturbed equilibrium or in activity by a circuit movement, the fact of direction in which involves polarity, or opposition of properties in opposite directions; also, by attraction for many substances, by a law involving attraction between surfaces of unlike polarity, and repulsion between those of like; by exhibiting accumulated polar tension when the circuit is broken; and by producing heat, light, concus

Depolarize :: Depolarize (v. t.) To deprive of polarity; to reduce to an unpolarized condition.

Polarity :: Polarity (n.) 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..

Polarization :: Polarization (n.) The act of polarizing; the state of being polarized, or of having polarity..

Mad :: Mad (superl.) Having impaired polarity; -- applied to a compass needle.

Bipolarity :: Bipolarity (n.) Bipolar quality.

Hysteresis :: Hysteresis (n.) A lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction; a temporary resistance to change from a condition previously induced, observed in magnetism, thermoelectricity, etc., on reversal of polarity..

Lodestone :: Lodestone (n.) A piece of magnetic iron ore possessing polarity like a magnetic needle. See Magnetite.

Polarily :: Polarily (adv.) In a polary manner; with polarity.

Solenoid :: Solenoid (n.) An electrodynamic spiral having the conjuctive wire turned back along its axis, so as to neutralize that component of the effect of the current which is due to the length of the spiral, and reduce the whole effect to that of a series of equal and parallel circular currents. When traversed by a current the solenoid exhibits polarity and attraction or repulsion, like a magnet..

Diamagnet :: Diamagnet (n.) A body having diamagnetic polarity.

Electro-polar :: Electro-polar (a.) Possessing electrical polarity; positively electrified at one end, or on one surface, and negatively at the other; -- said of a conductor..

Depolarization :: Depolarization (n.) The act of depriving of polarity, or the result of such action; reduction to an unpolarized condition..

Pole :: Pole (n.) One of the opposite or contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle..

Magnetite :: Magnetite (n.) An oxide of iron (Fe3O4) occurring in isometric crystals, also massive, of a black color and metallic luster. It is readily attracted by a magnet and sometimes possesses polarity, being then called loadstone. It is an important iron ore. Called also magnetic iron..

Astatic :: Astatic (a.) Having little or no tendency to take a fixed or definite position or direction: thus, a suspended magnetic needle, when rendered astatic, loses its polarity, or tendency to point in a given direction..
