Magnetic fluid, the hypothetical fluid whose existence was formerly assumed in the explanations of the phenomena of magnetism.Magnetic iron, or Magnetic iron ore. (Min.) Same as Magnetite.Magnetic needle, a slender bar of steel, magnetized and suspended at its center on a sharp-pointed pivot, or by a delicate fiber, so that it may take freely the direction of the magnetic meridian. It constitutes the essential part of a compass, such as the mariner's and the surveyor's. Magnetic poles, the two points in the opposite polar regions of the earth at which the direction of the dipping needle is vertical.Magnetic pyrites. See Pyrrhotite.Magnetic storm(Terrestrial Physics), a disturbance of the earth's magnetic force characterized by great and sudden changes. Magnetic telegraph, a telegraph acting by means of a magnet. See Telegraph.

(Mag*net"ic) n.

1. A magnet. [Obs.]

As the magnetic hardest iron draws.

2. Any metal, as iron, nickel, cobalt, etc., which may receive, by any means, the properties of the loadstone, and which then, when suspended, fixes itself in the direction of a magnetic meridian.

(Mag*net"ic*al*ly), adv. By or as by, magnetism.

(Mag*net"ic*al*ness), n. Quality of being magnetic.

(Mag`ne*ti"cian) n. One versed in the science of magnetism; a magnetist.

Animal magnetism, a force, more or less analogous to magnetism, which, it has been alleged, is produced in animal tissues, and passes from one body to another with or without actual contact. The existence of such a force, and its potentiality for the cure of disease, were asserted by Mesmer in 1775. His theories and methods were afterwards called mesmerism, a name which has been popularly applied to theories and claims not put forward by Mesmer himself. See Mesmerism, Biology, Od, Hypnotism.Terrestrial magnetism, the magnetic force exerted by the earth, and recognized by its effect upon magnetized needles and bars.

(Mag"net*ist), n. One versed in magnetism.

(Mag"net*ite) n. (Min.) 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.

(Mag"net*i`za*ble) a. Capable of being magnetized.

(Mag`net*i*za"tion) n. The act of magnetizing, or the state of being magnetized.
