In this work the authors draw upon their expertise in geophysical and astrophysical MHD to explore the motion of electrically conducting fluids, the so-called dynamo effect, and describe the similarities and differences between different magnetized objects.

Ausgehend von den Begriffen der Magnetohydrodynamik entwickeln die Autoren Konzepte, Experimente, um magnetische Effekte in stellaren Objekten, den galaktischen Dynamo sowie weitere magnetische Phänomene im Weltraum zu verstehen. Die Gültigkeit dieser Simulationen und Algorithmen für die moderne Astrophysik wird durch aktuelle experimentelle Ergebnisse gezeigt. Dies ist die zweite, aktualisierte und erweiterte Auflage dieser Darstellung eines Fachgebiets, dass sich an Astro- und Geophysiker, Wissenschaftler und Studenten gleichermaßen richtet und in den vergangenen Jahren deutlich an Einfluß gewonnen hat.
