magnetometer

[Eng. magnet, and Gr. metron=a measure.) An instrument for measuring any of the magnetic elements, as the dip, inclination, and intensity. A magnetized needle, isolated from all disturbing influences and suspended by untwisted silk, is used to detect the declination, and the delicate mode of adjustment permits any variation in this element to be observed. For observing the dip or inclination, the magnetized needle is balanced by knife-edges upon agate planes. măg-nět-o-mět-ric, a. [Pref. magneto-, and Eng. metric.] Pertaining to or employed in the measurement of magnetic force; obtained by the use of a magnetometer. Lat. Rotor mover move to momagnetovoltand măg-nět-o-mō-tor, s. [Pref. 4-9-5-2; luster, metallic to sub metallic; color and streak, black, opaque, but when in exce ively thin films sometimes nearly transparent, a smoky-brown color: fracture sub conchoidal and shining when pure. Strongly magnetic, and sometimes exhibiting polarity. Composition: Iron, 724; oxygen, 27.6, or sesquioxide of iron, 68.97; protoxide of iron, 31-03; represented by the formula FeOFe2O3. One of the most important of the ores of iron is found in beds often of immense extent in the Azoic rocks; that from Siberia and the Hartz district, Germany, afford the most powerfully magnetic varieties. Also found abundantly as sand, being derived from the weathering of crystalline and metamorphic rocks, in which it is distributed as minute crystals and grains. măg-net-iz-a-ble, a. [Eng. magnetiz (e); -able.] Capable of being magnetized. măg-nět-i-zā-tion, s. [English magnetiz(e); -ation. ] The act of magnetizing; the state of being magnetized. netized "The intensity body is the of quotient magnetization of its of moment a uniformly by the mag. vol ume."-Everett: C. G. S. System of Units (1875), ch. x. This may be effected by the action of the earth or by currents. măg-nět-ize, v. t. & i. [Eng. magnet; -ize; Fr. magnétiser; Sp. magnet i sar; Ital. magnetizzare.] A. Transitive : 1. To make magnetic; to communicate magnetic properties to. 2. To place under the influence of animal magnetism; to mesmerize. 3. To attract or draw, as with a magnet; to influence, to move. B. In trans.: To become magnetic; to acquire magnetic properties. †măg-nět-iz-eē, s. [Eng. magnetiz(e); -ee.] A person placed under the influence of animal magnetism.
