Book Description
Physics of Geomagnetic phenomena, Volume I covers the significant advances in geomagnetism and the penetrations into the generation of geomagnetic field phenomena. This volume is composed of three chapters. Chapter I deals briefly with the discovery and developments in geomagnetism, followed by discussions on some fundamental topics of the field, including the aurora and geomagnetic storms. This chapter also considers the instruments, geomagnetic stations, and the correlations between geomagnetic indices. Chapter II describes the magnetic properties of minerals and various processes of acquisition of remanent magnetization. This chapter also provides palaeomagnetic data for the direction and intensity of the geomagnetic field in ancient times. Chapter III explores geomagnetic variations caused by solar flares and eclipses. This book will prove useful to physicists, students in upper atmospheric and space topics, and scientists in allied fields with a background in geomagnetism.

Book Description
An analytic representation of the quiet daily variation of the geomagnetic field, Sq, was obtained for the North American region with a mean error of less than 10% of the daily variation range. The month by month 24-, 12-, 8-, and 6-hr Fourier components of the field in H, D, and Z were found to have significant annual and semiannual changes that, in general, agreed with the expectations for ionospheric current sources for the changes. Tables and computer programs are provided from which the quiet field representation may be constructed for any selected North American location. At the equator the Sq(H) variation was over 125 gammas and showed significant equinoctial maxima. At 30 deg to 40 deg the lowest values of Sq(H) (less than 20 gammas) were representative of the region of the ionospheric current vortex. Mid latitude Sq(D) values were about 50 gammas in range. Great enhancements of the daily field, particularly in Sq(H) and Sq(Z) occurred at high latitude with a strong summertime maximum range of about 90 gammas in Sq(H) at about 75 deg lat. Five-degree latitude representation of the quiet daily field change illustrate the variations occuring during the day and in different months of the year. (Author).

Book Description
An introductory guide to global magnetic field properties, Earth Magnetism addresses, in non-technical prose, many of the frequently asked questions about Earth's magnetic field. Magnetism surrounds and penetrates our Earth in ways basic science courses can rarely address. It affects navigation, communication, and even the growth of crystals. As we observe and experience an 11-year solar maximum, we may witness spectacular satellite-destroying solar storms as they interact with our magnetic field. Written by an acknowledged expert in the field, this book will enrich courses in earth science, atmospheric science, geology, meteorology, geomagnetism, and geophysics. Contains nearly 200 original illustrations and eight pages of full-color plates. * Largely mathematics-free and with a wide breadth of material suitable for general readers * Integrates material from geomagnetism, paleomagnetism, and solar-terrestrial space physics. * Features nearly 200 original illustrations and 4 pages of colour plates

Book Description
This survey summarizes what is known about the magnetic field of the earth, based on information available through 1971. Observed phenomena are described and interpreted in terms of the most widely accepted physical explanations. An overview of the geomagnetic field and its dynamic relationship with its terrestrial and interplanetary environment is first presented as briefly as possible, followed by more detailed descriptions of geomagnetic measurements and experimental methods, precise current models and past behavior of the main field, regular variations in the field resulting from the motion of the earth, disturbance variations of the field produced by interplanetary environment, and dynamic processes occurring in the outer magnetosphere. Extensive references is a replacement for Chapter 11 of Handbook of Geophysics and Space Environment (Shea L. Valley, ed.), Air Force Cambridge Research Laboratories and McGraw-Hill Book Co., New York, 1965.

Book Description
This volume provides a comprehensive view on the different sources of the geomagnetic field both in the Earth’s interior and from the field’s interaction with the terrestrial atmosphere and the solar wind. It combines expertise from various relevant areas of geomagnetic and near Earth space research with the aim to better characterise the state and dynamics of Earth’s magnetic field. Advances in the exploitation of geomagnetic observations hold a huge potential not only for an improved quantitative description of the field source but also for a better understanding of the underlying processes and physics. Key is the separation of the field sources in the observations, especially, but not solely, during times of quiet geomagnetic conditions, when the most subtle geomagnetic effects can be identified and become significant. The collected articles are based on the current constellation of ground and space observations, and on state-of-the-art empirical models and physics-based simulations. Thus, it provides an in-depth overview over recent achievements, current limitations and challenges, and future opportunities in the field of geomagnetism and space sciences.
