1850W. Whewell Let. (1876) II. 365 [To Faraday.] Will it not do to talk of iron, nickel, &c., as paramagnetic, and glass, phosphorus, &c., as diamagnetic? Then this new branch of science, for so, of course, it will soon become, will be Paramagnetism. 1851W. Gregory Lect. Anim. Magnet. p. xv, He does indeed propose to include, under the general term Magnetism, two forms of it: viz. Para-magnetism..and Dia-magnetism. 1877Le Conte Elem. Geol. (1879) 186 If the bar be slender, it..shows its paramagnetism by assuming the axial position. 1930[see ferromagnetism]. 1958N. Cusack Electr. & Magn. Prop. Solids xiii. 291 All matter possesses a basic diamagnetism but where there are carriers, e.g. free electrons in metals,..the orientation of the carriers in the field direction gives a paramagnetism which usually masks the diamagnetism. 1964J.
