It provides an enticing flavour of the modelling of a wide variety of electromagnetic phenomena. The text is intended primarily for advanced undergraduates and postgraduates in physics, geophysics and astrophysics. The essentially independent case studies make this book ideal to dip in and out of and to use as a source of reference on magneto-fluid phenomena .

He is also the main author of 22 papers published in the last 22 years in major physics, astrophysics, and plasma physics journals. He has worked in universities and research institutes in several countries. He is presently Visiting Professor in the Department of Earth and Planetary Sciences at McGill University in Montreal, Canada.

We are concerned here with macroscopic inter actions and, when the conducting fluid is a plasma, time scales are very much longer than the plasma period. Plasma periods vary widely, but are short, say 10 DEGREES DEGREES second. We prefer the term Magneto-F/i DEGREESZ(i-Dynamics (MFD) because the disci pline concerns mostly plasmas, various liquid conductors, and the liquid part of the Earth's core. It seems that the only applications of MFD to water are the induction of electric currents in the oceans by the Earth's magnetic field, and ship propulsion. But even MFD is not quite appropriate because that term also includes solid conductors that move in magnetic fields. This book is meant for graduate and upper-division undergraduate stu dents in Physics, Geophysics, and Astrophysics, as well as for practicing sci entists in these fields. This book is no more than a brief introduction to MFD because this vast subject is closely related to many others, namely Astrophysics, Elec trodynamics, Fluid Dynamics, Geophysics, Oceanography, Plasma Physics, Thermonuclear Fusion, etc. We sketch the fundamentals, and provide many Examples, as well as Case Studies related to natural phenomena. MFD sorely needs a rethink: it must of course be totally compatible with Physics. On the contrary, it is the custom to discuss the shapes of imaginary magnetic field lines, without ever referring to the required electric
