Book Description
Excerpt from Theory of Long-Period Magnetic Pulsations The magnetic pulsations have been known for over a hundred years. Historically such rapid changes in the earth's magnetic field were first reported by B. Stewart in 1861. He reported a large magnetic storm recorded at the Kew Observatory in England. It is shown in this report that the magnitude of the magnetic field fluctuations is of several hundred 7 (17 10'5gauss) and their typical time scale is on the order of few minutes. In particular, during the International Geophysical Year (igy) in 1957 - 1958 and in the succeeding years, the international collaboration on the earth's geophysical study became established and the global observation of the geomagnetic field variations such as magnetic pulsations began to be made.

Book Description
Electromagnetism and the Earth's Interior reviews the earth's magnetic fields in terms of physical processes that are occurring in the earth's interior. The book describes the distribution of the earth's magnetic field in terms of declination, horizontal intensity, and vertical intensity. The dynamo theory concerns the self-exciting electric generation in the interior of the earth, and can account for any geomagnetic secular variation. A workable laboratory model—a dynamo mechanism of Lowes and Wilkinson (1963) has a significant role on the dynamo theory for the model actually demonstrated Herzenberg's proof that was developed mathematically. The text also describes various aspects of long-term geomagnetic variations, such as the decrease in the dipole moment, the reversal of the geomagnetic field, the drift of eccentric dipole, the fluctuation in the length of day, and the geomagnetic secular variation. The book also investigates the possible effects of the ocean on geomagnetic variations. The characteristics of transient geomagnetic variations on islands can point to a possible special underground structure. The book is suitable for geologists, astrophysicists, seismologists, and students of the natural sciences.
