Rapid Variations of Earth’s Core Magnetic Field [PDF]

Surveys in Geophysics, 2022
AbstractEvidence of fast variations in the Earth’s core field are seen both in magnetic observatory and satellite records. We present here how they have been identified at the Earth’s surface from ground-based observatory records and how their spatio-temporal structure is now characterised by satellite data. It is shown how their properties at the core

Geomagnetic Jerks: Rapid Core Field Variations and Core Dynamics

Space Science Reviews, 2010
The secular variation of the core field is generally characterized by smooth variations, sometimes interrupted by abrupt changes, named geomagnetic jerks. The origin of these events, observed and investigated for over three decades, is still not fully understood.

Magnetic field of a core barrel

Geological Society, London, Special Publications, 1995
Abstract The magnetic field associated with a core barrel is almost entirely restricted to a small volume near to its tip and is insignificant within the barrel, except immediately adjacent to the wall. At the tip of the barrel the field is lowest along its axis and directed almost entirely parallel to it.
