Reversals of the earth's magnetic field

Physics Reports, 1971
Abstract One of the most intriguing problems in geophysics to-day is why the Earth's magnetic field reverses. This review summarizes the progress in our knowledge of the subject since Bullard's [1] Bakerian Lecture to the Royal Society in 1967. Reversals have played a major role in the changed outlook in geological thinking through the development of

Fall in Earth's Magnetic Field Is Erratic

Science, 2006
Earth's magnetic field has decayed by about 5% per century since measurements began in 1840. Directional measurements predate those of intensity by more than 250 years, and we combined the global model of directions with paleomagnetic intensity measurements to estimate the fall in strength for this earlier period (1590 to 1840 A.D.).

Study of the Earth's Magnetic Field

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The 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.

The Magnetic Field of the Earth’s Lithosphere

Space Science Reviews, 2010
The 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
