Geomagnetism deals with all aspects of the Earth's magnetic field, also called the geomagnetic field, that surrounds our habitat in the form of the magnetosphere. We cannot sense the geomagnetic field in any way, and instrumental measurements as continuous recordings or dedicated surveys are necessary to study it.

Geomagnetic prospecting consists of studying the local deformation of the Earth’s magnetic field produced by differences in the properties of surrounding materials. As fire heats the ground, which transforms the magnetic behaviour of the materials, it leaves an indelible magnetic imprint, the presence of which is revealed by a local deformation of the ...

Geomagnetic mapping for geomagnetic matching navigation
SPIE Proceedings, 2008Geomagnetic field is the basic physics field of the Earth, which can't be destroyed or changed in the foreseeable future. Geomagnetic field don't require special service, therefore, it can be considered as a solid source of navigation information.

The origin of geomagnetic jerks
Nature, 2002Geomagnetic jerks, which in the second half of the twentieth century occurred in 1969 (refs 1, 2), 1978 (refs 3, 4), 1991 (ref. 5) and 1999 (ref. 6), are abrupt changes in the second time-derivative (secular acceleration) of the Earth's magnetic field.

Studies on geomagnetic storm in relation to geomagnetic pulsation
Journal of Geophysical Research, 1958The existence of the earth's outer atmosphere, of which hydromagnetic oscillations forced by the corpuscular stream would give rise to geomagnetic pulsations, suggests the usefulness of studying the geomagnetic storm in relation to the geomagnetic pulsation, and, further, of improving the Chapman-Ferraro theory of the geomagnetic storm.

EDMOND HALLEY AND GEOMAGNETISM*
Nature, 1943This annual lecture, commemorating Edmond Halley, a great son of Oxford, is devoted to astronomy and terrestrial magnetism. My subject to‐day is Halley's geomagnetic work considered in its historical setting, but I will preface this by a few remarks on Halley as poet—a seldom remembered aspect of his remarkable versatility.Halley's Latin ...
