On interplanetary electric and magnetic fields

Solar Physics, 1982
A kinematic model of the stationary electromagnetic fields in interplanetary space with finite conductivity is considered. The electrodynamic problem is solved for a medium with uniform conductivity and radial plasma outflow from a spherical source. Simple analytical formulae are obtained for electric and magnetic fields, currents and charges in the ...

Polar substorm and interplanetary magnetic field

Planetary and Space Science, 1971
Abstract By means of the IMP 3 magnetic data, a study is made on the relationships between the interplanetary magnetic field and the development of polar substorm. It is found that an explosive growth of the westward electrojet tends to appear after the interplanetary magnetic field has directed southward for 1–2 hr.

Magnetic Fields in Interplanetary Space

Science, 1965
The brief period between the conception of the interplanetary magnetic field and conclusive proof of its existence has been an exciting one. Imaginative theoretical developments and careful experimental verification have both been essential to rapid progress.

Solar wind and interplanetary magnetic field

Reviews of Geophysics, 1967
A brief history is presented of some of our ideas regarding the solar wind. The basic physical principles of supersonic expansion are discussed. An analogy is drawn with the flow of an ideal gas through a rocket‐engine nozzle. Supersonic expansion of a stellar corona requires a stellar and coronal temperature lower than a specified maximum.

REGULATION OF THE INTERPLANETARY MAGNETIC FIELD

1992
In this study we use a recently developed technique for measuring the combined magnitudes of inward and outward (sunward and antisunward) pointing 2D magnetic flux in the ecliptic plane to examine (1) the long term variation of the amount of magnetic field open to interplanetary space and (2) the apparent rate at which coronal mass ejections (CMEs) may

Interplanetary magnetic field and solar rotation

Planetary and Space Science, 2012
Abstract This article presents analysis of interplanetary magnetic field (IMF) B measured at the L 1 point outside the geo-magnetosphere. The autocorrelation of daily values of the B x and B y component of the IMF reveal clear solar rotational modulation. The B z ( z -component of IMF) mostly do not show any such modulation.

Interplanetary Magnetic Fields and Cosmic Rays

Physical Review, 1955
The existence in the region around the sun of a field-free cavity in the galactic magnetic field seems indicated by the low-energy cosmic rays that reach the earth from the sun. Such a cavity would be produced by the solar corpuscular emission. A mean radius of the order of 200 times the distance from the sun to the earth may be estimated for this ...

Coronal and interplanetary magnetic field models

AIP Conference Proceedings, 1999
We provide an historical perspective of coronal and interplanetary field models. The structure of the interplanetary medium is controlled by the coronal magnetic field from which the solar wind emanates. This field has been described with “Source Surface” (SS) and “Heliospheric Current Sheet” (HCS) models.
