Power lines and the geomagnetic field
Bioelectromagnetics, 1995AbstractThe metric of prime interest in power line epidemiological studies has been AC magnetic intensity. To consider also possible geomagnetic involvement, the orientation of a long straight power line is examined relative to a uniform geomagnetic field (GMF) with dip angle α.

Spatial power spectra of the crustal geomagnetic field and core geomagnetic field
Physics of the Earth and Planetary Interiors, 1980Equations providing numerical values of the geomagnetic field spherical harmonic spatial power spectrum as defined by Lowes (1966, 1974) are obtained and this power spectrum is related to various other power spectra. Equations relating the spherical harmonic spatial power spectrum to average great circle power spectra for components of the vector ...

The Earth’s magnetic field represents the ultimate cause of rock magnetization. Here I describe the main internal source, or geodynamo, associated with convective currents in the external core, as well as the crustal field, generated by magnetized rocks, and the external magnetospheric and ionospheric sources. The concepts discussed in this chapter are

Abstract When averaged over a long enough interval of time, the Earth’s magnetic field is that of an axial dipole at the center of the Earth. The geocentric axial dipole hypothesis (GAD) forms the basis of understanding the ancient geomagnetic field.

History of the Geomagnetic Field
Journal of Applied Physics, 1969Direct measurements of the direction and strength of the earth's magnetic field have provided a knowledge of the field's form and behavior during the last few hundreds of years. For older times, however, it has been necessary to measure the magnetism of certain rocks to learn what the geomagnetic field was like. For example, when a lava flow solidifies

Space Science Reviews, 1976
In this review, an attempt has been made to describe the large variety of geomagnetic variations, both regular and irregular. After a brief description of the Earth and its environment, different types of quiet-day variations are described and present ideas regarding their possible mechanisms are discussed.
