Introduction to and modern account of magnetohydrodynamic turbulence, with astrophysical applications.Magnetic turbulence is the natural state of most astrophysical systems, such as stellar convection zones, stellar winds or accretion discs. It is also found in laboratory devices, most notably in the reversed field pinch. This book provides an introduction to magnetic turbulence, covering theory and applications in a pedagogical manner. After a brief outline of Magnetohydrodynamic theory, the book will discuss the macroscopic aspects of MHD turbulence, then cover the small-scale scaling properties. Applications are given to astrophysical and laboratory systems.Magnetic turbulence is the natural state of most astrophysical systems, such as stellar convection zones, stellar winds or accretion discs.
