Saturn’s magnetic field resembles that of an easy dipole, or bar magnet, its north-southern axis aligned to within 1° of Saturn’s rotation axis through the centre of the magnetic dipole at the centre of the world. The polarity of the area, favor Jupiter’s, is opposite that of Earth’s current field—i.e., the area lines emerge in Saturn’s north hemispbelow and also reenter the world in the southern hemispright here (see Earth: The geomagnetic area and magnetosphere). On Sarevolve a widespread magnetic compass would certainly suggest southern. Saturn’s field deviates measurably from a simple dipole field; this manifests itself both in a north-southern asymmetry and in a slightly greater polar surface field than is predicted by a pure dipole version. At Saturn’s one-bar “surface” level, the maximum polar area is 0.8 gauss (north) and also 0.7 gauss (south), exceptionally equivalent to Earth’s polar surconfront field, while the equatorial area is 0.2 gauss, compared via 0.3 gauss at Earth’s surconfront. Jupiter’s equatorial field, at 4.3 gauss, is more than 20 times more powerful than Saturn’s. If one represents Saturn’s magnetic area as created by a simple present loop via a specified magnetic minute (see magnetic dipole), then that magnetic minute is around 600 times Earth’s, whereas Jupiter’s magnetic moment is 20,000 times Earth’s.

Saturn’s magnetic area is generated by the fluid movements in the electrically conducting percent of the internal of the earth. This area, in which hydrogen exists in a fluid metallic state roughly a main rocky core, comprises the inner half of the world. Compared via Jupiter, less of Saturn’s mass and also volume is composed of this conducting metallic fluid, which may partly explain why Saturn’s magnetic area is a lot weaker. Jupiter’s interior is also hotter, so the fluid activities in its internal may be more vigorous, possibly contributing even further to the distinctions in the field toughness.

Saturn’s magnetospbelow is the teardrop-shaped area of area around the earth wright here the behaviour of charged pwrite-ups, which come mainly from the Sun, is dominated by the planet’s magnetic field rather than by interplanetary magnetic fields. The rounded side of the teardrop exoften tends sunward, creating a boundary, or magnetopause, with the outflowing solar wind at a distance of about 20 Sarevolve radii (1,200,000 km <750,000 miles>) from the centre of the planet but with considerable fluctuation as a result of variations in the press from the solar wind. On the oppowebsite side of Saturn, the magnetospright here is attracted out right into an tremendous magnetotail that exoften tends to excellent ranges.

Saturn’s inner magnetosphere, like the magnetospheres of Planet and Jupiter, traps a steady populace of very energetic charged pposts, greatly prolots, traveling in spiral paths alengthy magnetic field lines. These pwrite-ups form belts roughly Sarevolve similar to the Van Allen belts of Planet. Unfavor the situations of Earth and also Jupiter, Saturn’s charged-pshort article populace is significantly depleted by absorption of the particles onto the surfaces of solid bodies that orlittle bit within the area lines. Voyager data verified that “holes” exist in the particle populations on area lines that intersect the rings and the orbits of moons within the magnetospright here.

Saturn’s moons Titan and also Hyperion orbit at ranges close to the magnetosphere’s minimum dimensions, and also they sometimes cross the magnetopausage and also travel external Saturn’s magnetospbelow. Energetic charged particles trapped in Saturn’s outer magnetosphere collide via neutral atoms in Titan’s upper atmosphere and energize them, bring about erosion of the setting. A halo of such energetic atoms was oboffered by the Cassini orbiter.

Saturn possesses ultraviolet auroras created by the influence of energetic particles from the magnetospright here onto atomic and molecular hydrogen in Saturn’s polar environment. Ultraviolet imeras of Saturn taken by the Earth-orbiting Hubble Space Telescope in the late 1990s and also at an early stage 21st century flourished in capturing the auroral rings around the poles. These offered vivid evidence of the high symmeattempt of Saturn’s magnetic field and revealed details of the means the auroras respond to the solar wind and the Sun’s magnetic field.
