Foundations of Geomagnetism [Hardcover]

Presents the mathematical and physical tools needed to understand geomagnetism.The main magnetic field of the Earth is a complex phenomenon. To understand its origins in the fluid of the Earth's core, and how it changes in time requires a variety of mathematical and physical tools. This book presents the foundations of geomagnetism. The material is mathematically rigorous, but is logically developed and has consistent notation, making it accessible to a broad range of readers. Students and researchers will find this an invaluable resource in the appreciation of the mathematical and physical foundations of geomagnetism.The main magnetic field of the Earth is a complex phenomenon.
