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.
