magnetization|ˌmægnɪtaɪˈzeɪʃən|
[f. magnetize + -ation.]
1. The action of magnetizing or the condition of being magnetized.
1801Encycl. Brit. Suppl. II. 133/2 The striking it with a key will..make the process of magnetization very quick. 1832Nat. Philos. II. Electro-Magnet. x. 56 (U.K.S.) We shall call the action which produces an arrangement of poles similar to that resulting from a voltaic current, positive magnetization. 1845Todd & Bowman Phys. Anat. I. 239 Further tests of the presence of galvanic action are found in the magnetization of a steel needle placed within a coil. 1849S. R. Maitland Illustr. Mesmerism 74 M. Swedenborg being present, she begged him to increase the efficacy of the water, by joining in the magnetisation. 1868Athenæum 14 Mar. 390/2 Dr. Tyndall repeated Faraday's marvellous experiment—the magnetization of light. 1871Tyndall Fragm. Sci. (1879) I. xiii. 373 Previous to magnetization, a dipping needle..stands accurately level.
2. Special Comb.: magnetization curve, a graph of magnetic induction against magnetic field strength in the same region.
1890J. Hopkinson in Proc. R. Soc. XLVIII. 2 A magnetisation curve is all that I have obtained free from doubt; the sample was heated and its magnetisation determined at various temperatures for a force of 0·50. 1968C. G. Kuper Introd. Theory Superconductivity v. 86 Figure (5.5) shows a typical magnetization curve for a small cylinder in a transverse field. |
