(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.
2.
(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.

"Polarity" Quotes from Famous Books



... I do what nearly all of the doctors do, who use electricity with any regard to polarity; that is, if treating acutely inflamed eyes, for example, apply the negative pole to the eyes, thinking thereby to make them more negative; or, if treating amaurosis, apply the positive electrode to the affected parts, thinking thereby ...

... and I put him on my table alongside my tiny bust of Lincoln, which is the sacred place. I wish indeed those eyes could see within this shell of mine and tell what it is that twists my heart, physically turns it on its axis, so that its polarity is changed. From mystery to mystery we have traveled the past year, Anne, with her unfaltering trust, and I, a doubting Thomas. We came here for an operation, but the doctors somewhat doubt its wisdom at all, certainly not now, when pneumonia might befall. So after ten hard days ...

... is compound, and in such a direction that the two opposite horizontal poles have the same polarity; it follows from this that there will be two consequent poles in the iron, these being opposite in name to the horizontal poles and at right angles to them, viz., above and below the armature. Opposite sections of the commutator are connected together internally as ...

... of Leyden; extracts from it are given by Cavallo, in the second edition of his Treatise on Magnetism. From these extracts it is evident that he was acquainted with the attraction, repulsion, and polarity of the magnet, the art of communicating those properties to iron, the variation of the magnetic needle; and there are even some indications that he was acquainted with the construction of ...

... them. Einstein's 'Field Theory' practically proves it on the mathematical side. Now it is obvious that if gravitation is a form of magnetism—and if so it belongs to another plane of magnetic forces than that which we know and use—then the objects on a planet must have the opposite polarity from that of the planet itself. Since the globe is itself a magnet, with a positive and negative pole, its attraction power is not that of a magnet on any plane, because then the human race would be divided into two species, each polarized in the sign opposite to its own pole; when ...

... electromotive force and, second, suitable electrical connections for bringing that electromotive force to a point where it may be balanced against the unknown electromotive force of the couple. The two are connected with opposite polarity, or so that the two e.m.f.s oppose one another. So long as one is stronger than the other a current will flow through the couple; when the two are equal ...

... so treated, Hawthorne wrote frequently,—the group is an important one. The crowd attracted him by its polarity to his own solitude, and it is curious to observe how fond he was of the processional in his work. The simple illustration of this sort is "The Procession of Life;" here he marshals mankind, as with the power ...

... some stones lose their electricity; others develop it, others have it reversed, the positive becoming negative and vice versa; others again, when heated, become powerfully magnetic and assume strong polarity. When electricity develops under the influence of heat, or is in any way connected with a rising or falling of temperature in a body, it is called "pyro-electricity," from the Greek word "pyros," fire. The phenomenon ...

... two hundred Grove cups. The waves occupy about fifteen seconds each, ordinarily, but I have known them to last a full minute; though this is rare. As soon as one wave passes, another, of the reverse polarity, always succeeds. I have never known this to fail, and it may be set down as an invariable rule. When the poles of the aurora are in unison with the poles of the current upon the line, its effect is to increase the current; ...

... several of our letters have reciprocally miscarried. This may probably have the same fate; however, if it reaches Monsieur Sarrazin, I presume he will know where to take his aim at you; for I find you are in motion, and with a polarity to Dresden.

... of them in number. To what known cause can this exactly regular distribution of so many earthy strata of different colours surrounding the nucleus be ascribed? I don't know that any mineralogists have attempted an explanation of this wonderful phenomenon. I suspect it is owing to the polarity of the central nucleus. If iron-filings be regularly laid on paper by means of a small sieve, and a magnet be placed underneath, the filings will dispose themselves in concentric curves with vacant intervals between them. Now if these iron-filings are conceived to be suspended in a fluid, ...
