hydromagnetic, a.|ˌhaɪdrəʊmægˈnɛtɪk|
[f. hydro- (in hydrodynamic) + magnetic a. (in electromagnetic).]
Of, relating to, or involving an electrically conducting fluid (as a plasma or molten metal) acted on by a magnetic field.
1943H. Alfvén in Ark. f. Matem., Astr. och Fysik XXIXb. ii. 7 As the term ‘electromagnetic-hydrodynamic waves’ is somewhat complicated, it may be convenient to call the phenomenon ‘magneto-hydrodynamic’ waves. (The term ‘hydromagnetic’ is still shorter but not quite adequate.) 1955Proc. R. Soc. A. CCXXXIII. 310 Hydromagnetic waves in rare ionized gases are of interest in connexion with galactic magnetic fields, the heating of the corona and other astrophysical problems. 1963Alfvén & Fälthammar Cosmical Electrodynamics (ed. 2) iii. 73 In the sun all phenomena which are large enough to be observed visually from the earth are hydromagnetic, and the same holds for interstellar clouds. 1966Ferraro & Plumpton Introd. Magneto-Fluid Mech. (ed. 2) i. 13 It is this coupling between the electromagnetic and mechanical forces which characterizes hydromagnetic phenomena. 1973Nature 9 Nov. 58/2 Nobody can yet give a hydromagnetic description of the process by which the neutron star captures the plasma.
Hence ˌhydromagˈnetically adv., from the point of view of hydromagnetics.
1970Nature 4 Apr. 48/1 Warm plasmas are considered hydromagnetically. |
