Earth's core variability from magnetic and gravity field observations [PDF]
Solid Earth, 2023 The motions of the liquid within the Earth's outer core lead to magnetic field variations together with mass distribution changes. As the core is not accessible for direct observation, our knowledge of the Earth’s liquid core dynamics only relies on ...

Space weather effects on drilling accuracy in the North Sea [PDF]
, 2005 The oil industry uses geomagnetic field information to aid directional drilling operations when drilling for oil and gas offshore. These operations involve continuous monitoring of the azimuth and inclination of the well path to ensure the target is ...

Fluctuating gravity of Earth’s core [PDF]
, 2012 For centuries, we have known that Earth’s magnetic field varies with time. Edmond Halley (better known for his eponymous recurring comet) first recognized this time variation of magnetic compass needle direction and even offered a remarkable theory that ...

Induction effects on ionospheric electric and magnetic fields [PDF]
Annales Geophysicae, 2005 Rapid changes in the ionospheric current system give rise to induction currents in the conducting ground that can significantly contribute to magnetic and especially electric fields at the Earth's surface.

Scale disparities and magnetohydrodynamics in the Earth’s core [PDF]
, 2000 Fluid motions driven by convection in the Earth’s fluid core sustain geomagnetic fields by magnetohydrodynamic dynamo processes. The dynamics of the core is critically influenced by the combined effects of rotation and magnetic fields.

Study on Solar Proton Events in the Sun - Induced Earth’s Magnetic Field Atmospheric Variations
International Journal of Science and Engineering Invention, 2017 Estimation has been made for the most powerful solar proton events recorded in the Earth environment during 1976 - 2015. This study has been done in association with other related activities such as Sunspot numbers and Solar flare index, the Earth’s magnetic field variation H constant, Dst index, Ap index and Kp index data from Kyoto data centre and ...

Mantle Electrical Conductivity and the Magnetic Field at the Core–Mantle Boundary
Fluids, 2021 The Earth’s magnetic field is measured on and above the crust, while the turbulent dynamo in the outer core produces magnetic field values at the core–mantle boundary (CMB).

The rotating magnetocaloric effect as a potential mechanism for natural magnetic senses.
PLoS ONE, 2019 Many animals are able to sense the earth's magnetic field, including varieties of arthropods and members of all major vertebrate groups. While the existence of this magnetic sense is widely accepted, the mechanism of action remains unknown. Building from
