Magnetism is one of the most pervasive features of the Universe, with planets, stars and entire galaxies all having associated magnetic fields. All of these fields are generated by the motion of electrically conducting fluids, the so-called dynamo effect. The precise details of what drives the motion, and indeed what the fluid consists of, differ widely though. In this work the authors draw upon their expertise in geophysical and astrophysical MHD to explore some of these phenomena, and describe the similarities and differences between different magnetized objects. They also explain why magnetic fields are crucial in the formation of the stars, and discuss promising experiments currently being designed to study some of the relevant physics in the laboratory. This interdisciplinary approach makes the book appealing to a wide audience in physics, astrophysics and geophysics. Book News Annotation:
Magnetism makes stars, places planets, and marks galaxies. Each
entity has its own magnetic fields created by the motion of
electrically charged fluids in what has been called the "dynamo
effect." Rüdiger (astrophysics, U. of Potsdam) and Hollerbach
(applied mathematics, U. of Glasgow) describe how this effect works
on geophysical and astrophysical scales. Their topics include the
earth and planets, differential rotation theory, stellar and galactic
dynamos, magnetorotational instability, neutron star magnetism and
the magnetic Taylor-Conette flow. Their illustrations include a
number of startling color photographs.

Synopsis:
Electromagnetism is one of the four fundamental forces that bind the universe together. The study of planetary and solar magnetic fields explains natural magnetism as a phenomenon of magnetohydrodynamics. Thus dynamic magnetic fields are essential to explain the formation of stars and planets. Starting from the physical concepts of magnetohydrodynamics the authors adopt concepts, experiments and calculations for star formation and planetary evolution, the galactic dynamo and strong fields in astrophysics. New experimental results that impressively prove the validity of the powerful simulations and complex algorithms to modern astrophysics are provided for astrophysicists, geophysicists, researchers and students alike.
