Some evidence has been presented for the importance of the acceleration due to planetary precession (the Poincare acceleration) in the generation mechanism of the planetary magnetic fields. The formula relating the planetary magnetic fields to the parameters of rotation and precession of the planets ...
Planetary Magnetic FieldsSolar SystemDynamo TheoryJupiter (PlanetMagnetic DipolesMars (PlanetSolar 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 ...
A planet’s magnetic field emanates from its core and is thought to deflect the charged particles of thestellar wind, protecting the atmosphere from being lost to space. Magnetic fields, born from the cooling of a planet’s interior, could also protect life on the surface from harmful radiati...
Knowledge of geomagnetism and its effects was recently much augmented during the IGY; when added to what is known of stellar fields, interplanetary fields, and meteoric magnetism, and combined with magnetic theory, this knowledge not only suggests that much may be learned of our neighbors in spac...

Planetary magnetic fields have another effect that may actually be more important in keeping a planet habitable. Earth's magnetic field prevents the solar wind from interacting directly with its atmosphere. (This statement is equivalent to saying that it protects Earth from solar cosmic rays.) Mars...
Geometrical properties of three-dimensional reconnecting magnetic fields with nulls This paper is concerned with the geometrical aspects of the reconnection of magnetic field lines. Reconnection is associated with discontinuities in the ov... JM Greene - 《Journal of Geophysical Research Space Physics》 ...
Insights Into Planetary Magnetic Fields “‘Diamond rain’ on icy planets presents us with an intriguing puzzle to solve,” said SLAC scientist Mungo Frost, who led the research. “It provides an internal source of heating and transports carbon deeper into the planet, which could have a signific...
It contains:electromagnetic radiation(photons 光子),hot plasma(等离子体)(electrons, protons(质子) and other ions(离子))also known as the solar wind, cosmic rays,microscopic dust particles, and magnetic fields(primarily the Sun's).While the Sun's radiation is obvious, the other components of ...
"In our circle of close neighbors—the Moon, Mars, Venus—we're the only planet with a magnetic field that's been going strong since the beginning and remains active today," Lapôtre said. But Jupiter-sized exoplanets orbiting close to their star have been identified with magnetic fields, ...
