Topology of High-Latitude Magnetospheric Currents

2011
The structure and localization of high latitude transverse and field-aligned currents are analyzed using the data from the Themis satellite mission. A number of evidences resumed in this paper, including daytime compression of magnetic field lines and the existence of magnetic field minima far from the equatorial plane make necessary to reanalyze the ...

Field-aligned currents in the magnetosphere

Journal of Geophysical Research, 1967
Certain satellite and terrestrial observations of transient magnetic fluctuations show a high degree of localization, while other observations are of a definite worldwide character. The worldwide fluctuations in the magnetic field are probably well explained in terms of hydromagnetic waves propagating through the magnetosphere in modes with the wave ...

Magnetospheric topology of fields and currents

1984
The interaction of the solar wind with the magnetosphere is examined from the standpoint of fundamental processes in physics and, whenever possible, observational data. A conceptual model is developed which incorporates several features of the magnetosphere that are still open to debate, such as open magnetic field lines in the polar cap and a boundary

Equatorial current sheet in the magnetosphere

Journal of Geophysical Research, 1972
The delta B distribution deduced from the Ogo 3 and 5 satellites shows large field depressions in the equatorial region inside the plasmasphere. On the basis of the delta B distribution, it is shown that what is usually considered the quiet-time ring current is an equatorial sheet current that is an extension of the neutral sheet current in the ...

Electric Current Structure of the Magnetosphere

1975
The first approach to magnetospheric theory was based on a mathematically elegant formalism which, however, was highly idealized and derived without contact with experiment. It led to the Chapman-Ferraro and later to the Axford-Hines theories. The laboratory confrontation between this formalism and the real plasma took place when an attempt was made to

Currents and flows in distant magnetospheres

2000
Space scientists have explored, described, and explained the terrestrial magnetosphere for four decades. Rarely do they point out that the planetary and solar wind parameters controlling the size, shape, and activity of Earth's magnetosphere map out only a small portion of the space of dimensionless parameters that govern magnetospheric properties ...

Three‐Dimensional Currents in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, 2019
AbstractObservations of Saturn's magnetic field from July 2004 to December 2016 have been combined to allow a numerical calculation of ∇ × B throughout the magnetosphere, thus permitting the first global mapping of Saturn's currents in three dimensions.

Field Aligned Currents in the Magnetosphere

1974
This paper deals with field aligned currents in general. Specific topics are: a brief review of the well established features; new results from the triaxial magnetometer experiment on the TRIAD satellite; comparison of the results from a variety of studies; relation of field aligned currents to other areas of research; and comments on future studies.

Global Magnetospheric Electric Fields and Currents

1984
In the foregoing chapter, we made simple estimates of electric fields and currents within the magnetosphere. We quantify in this chapter the global electric field and current configuration within the inner magnetosphere (r < 15a) and its magnetic manifestation on the ground [see also Gurevich et al. (1976) and Pudovkin (1974)].
