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 current sheets

Radio Science, 1973
A review is presented of theories and observations of current sheets in the magnetosphere, emphasizing the magnetopause and tail current sheets.Theoretical models of the magnetopause current sheet can be divided into two types: specular reflection and fluid models containing no external magnetic field, and models with an interplanetary/magnetosheath ...

The current sheets in the magnetosphere of a pulsar

Astrophysics and Space Science, 1987
This paper presents a possible emission mechanism based on the idea of the current sheet of magnetohydrodynamics. Since the excited plasma turbulences result in the anomalous resistance near the light cylinder of a pulsar, the frozen-in condition is partly dissolved.

Variability of the electric currents in the magnetosphere

Physics and Chemistry of the Earth, Part C: Solar, Terrestrial & Planetary Science, 2000
Abstract We used several thousand magnetic measurements in the distant magnetosphere to study differential responses of the magnetospheric currents to various geophysical parameters. It is shown that the growth of the solar wind dynamic pressure intensifies the magnetopause and magnetotail currents.

Currents in Mercury's magnetosphere

2000
Electric currents play an important role in the terrestrial magnetosphere as an agent to couple different plasma regimes and to mediate stresses. Much effort has been put into unravelling the structure of the current system of our planets magnetosphere.

A model of the distributed magnetospheric currents

Journal of Geophysical Research, 1974
A model of the quiet time ring current and the tail currents has been developed for quiet magnetic conditions and perpendicular incidence of the solar wind on the main (dipolar) field of the earth. Previous work of several authors has shown that these distributed currents flow throughout the magnetosphere and that they are produced by the drift of ...

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 ...

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

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

Current Models of Pulsar Magnetospheres

2010
Pulsar magnetospheres are filled with plasma, and the presence of plasma affects all macroscopic and microscopic properties of the magnetosphere. Although this simple fact was well known since the early days of pulsar research, the ability to quantitatively model plasma effects has emerged mainly in the last decade.
