The intensity of the planetary magnetic field in the outer space has been shown to be proportional to the Poynting vector flux on the surfaces of planetary cores. The flux is expressed in its explicit form through the parameters of rotation, precession, sizes, density, and conduction of ...
Solar Magnetic FieldVenus (PlanetThe magnetic fields of planets are considered, taking into account the history of the geomagnetic field characteristics, the magnetic field of Jupiter, the magnetic properties of Mars, the significance of a failure to detect signs of a magnetic field during the ...
magnetic field. Moreover, unmagnetized planets in the flowing solar wind carve out cavities whose properties are sufficiently similar to those of true magnetospheres to allow us to include them in this discussion. Moons embedded in the flowing plasma of a planetary magnetosphere create interaction ...
Finally, the modeling of the planetary magnetic field and magnetospheric plasma at these two planets has also been considerably improved. To organize the ... Zarka,Philippe - 《Journal of Geophysical Research》 被引量: 560发表: 1998年 Global spherical harmonic models of the internal magnetic field...

Also, the lack of a detectable intrinsic magnetic field of Io8 does not favour a fully molten interior. I have previously pointed out that Io's and Europe's orbiting in the strong magnetic field of Jupiter may cause their volcanic activity7 and this can be confirmed by simple calculations8...
The collapse of the Earths magnetic field-which guards the planet and guides many of its creatures-appears to have started about 150 years ago,the New York Times reported last week. The fields strength has decreased by 10 or 15 percent so far and this has increased the debate over whether ...
Unlike Earth’s magnetic field, the fields around these icy planets are not symmetrical and don’t extend from each pole. These properties suggest that the fields aren’t generated in the planetary core but in a thin layer of conducting material. ...
The fields strength has decreased by 10 or 15 percent so far and this has increased the debate over whether it signals a reversal of the planets lines of magnetic force. During a reversal,the main field weakens,almost vanishes,and reappears with opposite polarity(极). The transition would ...
