Review
From the Reviews
"This layman's non-technical description of the Earth's magnetic field is long overdue. Dr. Campbell has done an excellent job of not only describing the scientific nature of this area of science, but also puts the understanding at the level of the majority of the public."
--Joe Hirman, Chief Forecaster, Space Environment Forecast Center, NOAA
"This book is written by a world-renowned scientist and provides a wealth of scientific information about magnetic fields, in a way that is state-of-the-science yet fun to read. Dr. Campbell carries an unbridled enthusiasm for geomagnetism, which he is willing and able to share with scientists and non-scientists alike, and he does it with superb clarity, simplicity and practicality."
--Herbert W. Kroehl, Secretary General, International Association for Geomagnetism and Aeronomy
From the Back Cover
We are now in the years of maximum solar activity. Spectacular outbursts of particles and fields will bombard the Earth and continue at high levels for the first few years of the millennium. In this period of striking auroras and satellite-damaging magnetic storms, it is natural to wonder about the magnetic fields that guide solar practices to create such astonishing displays. This book takes the reader on a tour through the Earth's magnetic fields with a minimum of jargon and mathematical detail.
Journey with the author from historical observations of the magnetic field and magnetic applications in the modern world through the Earth's principle magnetic field to understand why there are so many magnetic pole locations. The everyday main field and quiet-time variations that are superimposed on the main field together form a baseline from which we measure the magnificent but potentially damaging magnetic storms. Learn how these spectacular field disturbances start from blasts of particles ejected from our Sun.

Wallace Hall Campbell is guest scientist at the Solar-Terrestrial Physics Division of the National Oceanic and Atmospheric Administration in Boulder, CO. His current appointment follows a distinguished career as a research geophysicist within the geomagnetism group at the USGS and many years of upper atmosphere research in geomagnetism for NOAA. His research interests continue to be ionspheric currents, electrical conductivity of the Earth, geomagnetic storms, pulsations, and field applications. Dr. Campbell wrote and co-authored two major textbooks and more than a hundred publications in geomagnetism.
