traversed by a current the solenoid exhibits polarity and attraction or repulsion, like a magnet.

The somnolent state induced by animal magnetism. Thomas (Med. Dict.).

A tendency in the end of a magnetic needle to point toward the south pole. Faraday.

r head, having through it an insulated wire which is connected with the induction coil or magneto circuit on the outside, and forms, with another terminal on the base of the plug, a spark gap inside the cylinder.

oy of iron with an iron carbide. Steel, unlike wrought iron, can be tempered, and retains magnetism. Its malleability decreases, and fusibility increases, with an increase in carbon.

onal excitement; sensibility, in its broadest acceptation; impressibility; sensitiveness. Magnetic susceptibility (Physics), the intensity of magnetization of a body placed in a uniform megnetic field of unit strength. Sir W. Thomson.

roduced in two separate circuits. In the receiver these variations are utilized by electromagnetic devices and levers to move a pen as the pencil moves. --Tel`au*tog"ra*phist (#), n.

An instrument for recording and reproducing sound by local magnetization of a steel wire, disk, or ribbon, moved against the pole of a magnet connected electrically with a telephone receiver, or the like.

An hypothesis of animal magnetism propounded by Dr. Keiser, in Germany, in which the phenomena are ascribed to the agency of a telluric spirit or influence. [R.] S. Thompson.

cial days, designated by scientists of different nations or stations, for making synoptic magnetic, meteorological, or other physical observations.

A spherical magnet so placed that its poles, equator, etc., correspond to those of the earth. [Obs.] Chambers.

Containing or affording titanium; as, titaniferous magnetite.

rsion balance (Physics.), an instrument for estimating very minute forces, as electric or magnetic attractions and repulsions, by the torsion of a very slender wire or fiber having at its lower extremity a horizontal bar or needle, upon which the forces act. -- Torsion scale, a scale for weighing in which the fulcra o…

t of tungsten, noted for tenacity and hardness, even under a considerable degree of heat. Magnets made of it are said to be highly permanent. It often contains manganese.

g the use of only one thread, wire, fiber, or the like; as, unifilar suspension. Unifilar magnetometer (Physics), an instrument which consists of a magnetic bar suspended at its center of gravity by a long thread, constituting a delicate means for accurately measuring magnetic intensities, also for determining declinat…

Unipolar induction (Elec.), induction, as in a conducting circuit, by only one pole of a magnet. -- Unipolar stimulation (Physiol.), the simulation sometimes produced when one electrode of an induction apparatus is applied to a nerve; -- called also unipolar induction action. Du Bois-Reymond.

res. -- Variation of the needle (Geog. & Naut.), the angle included between the true and magnetic meridians of a place; the deviation of the direction of a magnetic needle from the true north and south line; -- called also declination of the needle.

An instrument for comparing magnetic forces, esp. in the earth's magnetic field.

s compass with a vernier for the accurate adjustment of the zero point in accordance with magnetic variation. -- Vernier transit, a surveyor's transit instrument with a vernier compass.

ound at Vichy, France. It is essentially an effervescent solution of sodium, calcium, and magnetism carbonates, with sodium and potassium chlorides; also, by extension, any artificial or natural water resembling in composition the Vichy water proper. Called also, colloquially, Vichy.
