`The book should be eminently suitable for a course in solar physics. Also it provides a comprehensive review of present magnetohydrodynamical models in solar physics, which will be quite useful for workers in the field. Finally, the book is strongly recommended to the rapidly growing number of astrophysicists studying magnetically active stars.' Science `...belongs on the desk of every astrophysicist interested in active objects, whether stars or galaxies. It should go without saying that the book is also an excellent text for a graduate on magnetohydrodynamics.' Nature `Professor Priest has succeeded in writing a lucid and thorough introductory in the fascinating field of Solar Magnetohydrodynamics that is of great value to students and researchers in the field. It is easily accessible to researchers in peripheral astrophysical disciplines such as stellar atmospheres and extragalactic physics. This monograph can be recommended as the textbook in this field.' Space Science Reviews `...only very rarely do I feel delighted to receive a particular book. Eric Priest's book is nevertheless one such instance. It is a very solid production both on the part of the author who has provided the best part of 500 pages and the publisher who has matched the author's effort with a well presented text and illustrations.' Planetary Space Science `Professor Priest had constructed an impressively coherent textbook. As an account of solar magnetism, or a demonstration of the applied-mathematical approach in astrophysics it can be strongly recommended.' Journal of Fluid Mechanics, 155 (1985)
