magnetohydrodynamics, n. pl. (const. as sing.)|mægˌniːtəʊhaɪdrəʊdaɪˈnæmɪks|
[f. prec.: see -ic 2.]
The more usual name for hydromagnetics n. pl.
1950Sci. Amer. Oct. 39/3 Among these [theories] one can mention the magneto-hydrodynamics of charged particles proposed by the Swedish cosmologist H. Alfven. 1958Observer 7 Sept. 13/5 ‘Magnetohydrodynamics’, a branch of theoretical physics which combines classical theory of the behaviour of water and of magnetic fields,..is becoming one of the most elaborate and enthralling branches of science. 1973M. Harwit Astrophysical Concepts vi. 194 Magnetohydrodynamics..tells us that the presence of a force, such as a gravitational or electrostatic force, acting normal to the magnetic field, can produce a drifting motion.
Hence magˌnetohydrodyˈnamicist, one who studies magnetohydrodynamics.
1955Sci. Amer. Feb. 41/1 How the corpuscles travel through space is still in dispute. The Alfvén school of ‘magneto-hydrodynamicists’, for instance, maintains that the Chapman–Ferraro theory is basically incorrect, and that the solar corpuscles, as well as cosmic rays, are accelerated by magnetic and electrical fields in space. |
