磁动力学导论

　　magnetic fields influence many natural and man-made flows.they are routinely used in industry to heat， pump， stir andlevitate liquid metals.there is the terrestrial magnetic fieldwhich is maintained by fluid motion in the earth's core， the solarmagnetic field which generates sunspots and solar flares， and thegalactic field which influences the formation of stars.this is anintroductory text on magnetohydrodynamics （mhd） - the study of theinteraction of magnetic fields and conducting fluids.this book is intended to serve as an introductory text foradvanced undergraduate and postgraduate students in physics，applied mathematics and engineering. the material in the text isheavily weighted towards incompressible flows and to terrestrial（as distinct from astrophysical） applications. the final sectionsof the text also contain an outline of the latest advances in themetallurgical applications of mhd and so are relevant toprofessional researchers in applied mathematics， engineering andmetallurgy.
