The Magnetic Field of the Earth’s Lithosphere
Space Science Reviews, 2010The lithospheric contribution to the Earth's magnetic field is concealed in magnetic field data that have now been measured over several decades from ground to satellite altitudes. The lithospheric field results from the superposition of induced and remanent magnetisations. It therefore brings an essential constraint on the magnetic properties of rocks

Study of the Earth's Magnetic Field
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021The study of Earth's magnetic field is described in the paper. The position of magnetic poles is very important knowledge for all of branch of human life. It was noted the magnetic poles are drifted constantly. The velocity of poles drift reaches the value in 60 km per year.

Geomagnetic micropulsations are short period (usually of the order of seconds or minutes) fluctuations of the Earth’s magnetic field. They are transitory variations of small amplitude (usually less than one part in 104 of the Earth’s main field) and leave no permanent effect on the field. Like longer period disturbances such as magnetic storms they are

This chapter deals with the basics of the Earth’s magnetic field. Hydromagnetic dynamo operating in the Earth’s fluid outer core is treated as a main source of the Earth’s magnetic field. Here we discuss the interaction between solar wind and the Earth’s magnetosphere that forms the global magnetospheric configuration as well as the impacts of the ...

Recent studies of the time averaged field (TAF) shows that the paleofield of Earth is much less variable than the present magnetic field, which is asymmetric between the northern and southern hemispheres. The VGP dispersion in the southern hemisphere is much larger than in the northern hemisphere.

Precession and the Earth's Magnetic Field [PDF]
Nature Physical Science, 1972 IT is generally agreed that the Earth's principal magnetic field arises from a dynamo action in the fluid and electrically conducting core, although the origin of motions in the core is still a matter for speculation. Only two mechanisms seem to be possible-thermal convection in the core or precession of the Earth1.

The Earth’s magnetic field is generated in the fluid region deep inside the Earth. Heat convection, buoyancy forces and planetary rotation cause the iron-rich fluid in the outer core to flow in a complex way and the movement of this electrical conductor through existing magnetic field generates electrical current.

The Earth's Electric and Magnetic Fields [PDF]
Nature, 1923 II. TWO of the most characteristic features of the earth's magnetism are the non-coincidence of the magnetic and geographic axis, and the secular variation. While a theory which is to claim any degree of completeness must account for these, one cannot resist the temptation of searching for any sort of phenomenon capable of giving a field of the order ...
