Book Description
This is the first book to review all the fields of equatorial electrojet phenomena and their relevant theories in one volume. In certain relevant sections, the book discusses both the equatorial electrojet and the world-wide parts of the Sq current systems. Onwumwchili is an internationally known and highly respected expert in the equatorial electrojet field- a brand of geomagnetism.

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
A computer program which calculates electron and ion densities, ionospheric conductivities, electric fields and currents, and magnetic variations in regions near the magnetic equator is described in detail. It is also explained how this numerical model can be used to deduce F-region vertical plasma drifts in the equatorial ionosphere from observed magnetic variations at ground level. (Author).

Book Description
The equatorial electrojet (EEJ) is an intense electric current that flows in the ionosphere in a narrow zone above the magnetic dip equator during the daytime. The electrojet current produces a large enhancement of the surface component of the geomagnetic field at and in the vicinity of the dip equator. The EEJ is most intense around local noontime and appears to be more stable than other ionospheric current systems. This report presents a brief overview of the characteristics of the EEJ, including its location, electron density profile, current distribution, and magnetic field. In addition, the diurnal and seasonal variations of the EEJ are discussed. The relationship of the EEJ to the worldwide dynamo current system is discussed, in addition to a comparison with the aurora electrojet (AEJ). A derivation of the EEJ current distribution is presented that is based on an anisotropic conductivity model of the ionosphere. A summary of several experiments involving the generation of low4requency signals from a heated and modulated EEJ is also given. It is anticipated that this report will provide helpful background information to scientists and engineers engaged in the development of future experiments that involve the transmission of signals in the ELF and VLF frequency bands from a heated and modulated EEJ.
