The phenomena of the rotation of movable conductors, carrying currents, about lines of magnetic force are well known. One form of experiment, commonly called the rotating spark, presents, beside the actual rotation, some peculiar features which do not appear to have been noticed in detail. The instrumental arrangements consist of a partially exhausted chamber with a platinum point for one terminal, a ring for the other, and the intervening air or other gas for the movable conductor. The chamber is made in the form of a double cylinder, so that a magnet inserted through the ring may reach nearly to the point. The discharge then passes between the point and the ring, and revolves about the magnet according to Ampere’s law. But beside the rotation, and even when, through weakening of the magnet, rotation does not actually take place, the spark, when carefully observed, is seen to assume a spiral form ; and the spiral is right-handed or left-handed according to both the direction of the current and the magnetic polarity. This effect is particularly noticeable if the magnetic pole be inserted only a short distance beyond the ring. The discharge is then seen to spread itself out sheetwise on the ring in the direction in which rotation would take place. The edge of the sheet is in the form of a helix.

The Way

On a subject so obscure as electro-magnetism, and connected by analogies more or less distinct with the doctrines of heat, light, electricity, and chemical attraction, it is not difficult to frame hypotheses ; but the science is in a state too near its infancy to expect the developement of any satisfactory theory ; and its progress can only be ensured by new facts and experiments, which may prepare the way for extensive and general reasonings upon its principles. Influenced by this opinion, I am induced to lay before the Society an account of an electro-magnetic phenomenon I observed about fifteen months ago in the laboratory of the Royal Institution, and which I have lately had an occasion of witnessing in a more perfect manner, through the kindness of Mr. Pepys, by the use of a large battery, constructed under his directions for the London Institution, and containing a pair of plates of about two hundred square feet. In describing this phenomenon, I shall not enter into very minute details, because the experiments, which led to the discovery of it, are very simple, and, though more distinct with a large apparatus, yet it may be observed by the use of a pair of plates containing from ten to fifteen square feet. Immediately after Mr. Faraday had published his ingenious experiments on electro-magnetic rotation, I was induced to try the action of a magnet on mercury connected in the electrical circuit, hoping that, in this case, as there was no mechanical suspension of the conductor, the appearances would be exhibited in their most simple form; and I found that when two wires were placed in a basin of mercury perpendicular to the surface, and in the voltaic circuit of a battery with large plates; and the pole of a powerful magnet held either above or below the wires, the mercury immediately began to revolve round the wire as an axis, according to the common circumstances of electro-magnetic rotation, and with a velocity exceedingly increased when the opposite poles of two magnets were used, one above, the other below.

Electro Magnetic

About fifteen months ago it occurred to Sir Humphry Davy to try the action of a magnet upon mercury, connected in the electric circuit; and having very lately had occasion to repeat the experiment in a more perfect manner, by the aid of a battery, consisting of a single pair of plates of about 100 square feet, constructed for the London Institution, under the direction of Mr. Pepys, he is induced to lay the result of the experiment before the Royal Society, as presenting a phenomenon which may prove important hereafter in its relations to the theory of electro-magnetism. When two wires were placed in a basin of mercury, perpendicular to the surface, and in the voltaic circuit of the above-mentioned battery, the mercury revolved according to the common law of electro-magnetic rotation, upon presenting a magnet either above or below the wires; and the velocity was increased by using the opposite poles of two magnets, one above and the other below the mercury. When the pole of the magnet was held above the mercury, and between the two wires, the circular motion ceased, and currents took place in the mercury in opposite directions. These and other circumstances induced Sir Humphry Davy to believe that the passage of the electricity through the mercury, produced motions independent of the magnet, and that the rotations described were owing to a composition of forces; and, moreover, that such motions would, from the position of the wires, occur chiefly at the lower surface of the mercury; he therefore inverted the form of the experiment, bringing the copper wires through two holes in the bottom of a glass basin, with so much mercury in it as to stand one tenth of an inch above the polished ends of the wires. Upon making the communication with the battery, the surface of the mercury was elevated into a small cone above each of the wires, from which waves flowed off in all directions, the only apparent point of rest being central, between the wires. These cones were diminished by the approximation of the pole of a magnet, which produced rotation, and on bringing it near enough, a depression of the mercury above the pole. The above phenomenon appeared, independent of any elevation in the temperature of the mercury, nor can it be attributed to electric repulsion. It must be referred to forces producing motions in right lines, or undulations from the surfaces of the wires as a centre; and it seems, says the author, strongly opposed to the idea of the electro-magnetic results, being produced by the motion of a single imponderable fluid.
