This unified, interdisciplinary, and comprehensive collection provides a foundation in dynamo theory before moving on to modeling aspects of natural dynamos. It introduces governing equations, outlines the kinematic dynamo theory, covers nonlinear effects, and discusses fluid dynamics. The book then describes the Earth's magnetic field and the current understanding of its characteristics. Subsequent chapters examine other planets in our solar system and the magnetic field of stars, including the sun. The book also addresses dynamo action on the large scale of galaxies, presents modeling experiments of natural dynamos, and speculates about future research directions. Book News Annotation:
Magnetohydrodynamics (MHD) is the study of magnetic field generation
through the motion of electrically conducting fluids. The field is
part of what relatively little we know about how astrophysical
bodies, including planets and whole galaxies, generate magnetic
fields. This collection of eight integrated articles provide a broad
coverage of the central issues for the benefit of researchers and
advanced students. Topics include foundations of dynamo theory,
including self-excited dynamo action, nonlinearity and saturation,
and dynamics of rotating fluids; natural dynamos and models,
including the geodynamo, planetary dynamos, stellar dynamos, and
galactic dynamos; and results of recent experiments. Appendices
include materials on poloidal-toroidal coordinates and Taylor's
constraint. Although contributors assume readers have a solid
background in mathematics and fluid mechanics, prior knowledge of
MHD, dynamo theory, geophysics and astrophysics is not required.

Synopsis:
Dynamo theory suggests that the continuous regeneration of a magnetic field in an astrophysical body occurs due to the motion of highly conductive fluids, such as the liquid iron in the Earth's outer core or the ionized gas of the sun, across an existing magnetic field. Mathematical Aspects of Natural Dynamos explores the mathematical aspects of these self-sustaining dynamos. Chapters highlight nonlinearities and saturation, dynamics of rotating fluids, and planetary, stellar, and galactic dynamos. The authors include a comprehensive survey and description of experimental results. This book is an invaluable resource for professionals and students interested in the fluid mechanics of astrophysics and geophysics.
