Quick Answer: How big is Saturn’s magnetic field?

The magnetic field strength at Saturn’s equator is about 21 μT (0.21 G), which corresponds to a dipole magnetic moment of about 4.6 × 1018 T•m3. This makes Saturn’s magnetic field slightly weaker than Earth’s; however, its magnetic moment is about 580 times larger.

Why is Saturn’s magnetic field 20 times weaker than Jupiter’s?

Jupiter’s equatorial field, at 4.3 gauss, is more than 20 times stronger than Saturn’s. … Compared with Jupiter, less of Saturn’s mass and volume consists of this conducting metallic fluid, which may partly explain why Saturn’s magnetic field is much weaker.

Why does Saturn have such a strong magnetic field?

Saturn’s magnetic field is created as material cycles deep within the planet’s fluid interior. Outside Saturn’s magnetosphere, a million-mile-per-hour flow of electrically charged particles (electrons and ions) from the sun, called the solar wind, spreads out through the solar system.

What is the cause of the immense magnetic fields of Jupiter and Saturn?

One such a layer inside Jupiter and Saturn is metallic hydrogen, and the electric current caused by swirling movements in this substance produces a magnetic field so large that the tail of Jupiter’s magnetic field reaches the edge of Saturn’s orbit!

What planets have a magnetic field?

Probes found that Mars and Venus do not have a significant magnetic field. Jupiter, Saturn, Uranus, and Neptune all have magnetic fields much stronger than that of the Earth. Jupiter is the champion- having the largest magnetic field. The mechanism that causes their magnetic fields is not fully understood.

Does Saturn give off radiation?

Saturn, however, has the second radiation belt discovered by Cassini in 2004 and located just inside the innermost D Ring. … The saturnian radiation belts are generally much weaker than those of Jupiter and do not emit much microwave radiation (with frequency of a few Gigahertz).

Does Saturn support life?

Saturn cannot support life as we know it, but some of Saturn’s moons have conditions that might support life.

Do any moons have magnetic fields?

The Moon no longer has a magnetic field. When the Moon had a magnetic field, it would have been shielded from incoming solar wind, as shown in this illustration.

Does Venus have a magnetic field?

Venus is a rarity among planets – a world that does not internally generate a magnetic field. Despite the absence of a large protective magnetosphere, the near-Venus environment does exhibit a number of similarities with planets such as Earth.

Does Jupiter have magnetic field?

Jupiter’s Magnetosphere

Some 20,000 times stronger than Earth’s magnetic field, Jupiter’s magnetic field creates a magnetosphere so large it begins to avert the solar wind almost 3 million kilometers before it reaches Jupiter.

Does the sun have a magnetic field?

Electric currents inside the sun generate a magnetic field that spreads throughout the solar system. The field causes activity at the surface of the sun, surging and ebbing in a regular cycle. … A solar wind composed of charged particles carries the magnetic field away from the sun’s surface and through the solar system.

Is there water on Saturn?

There is water, but not very much. Once you get away from Saturn itself, though, the nearby area has plenty of water. Saturn’s rings are almost entirely made of water ice, in chunks ranging in size from dust to house-sized boulders. And all of Saturn’s moons have large quantities of water ice.

Which planet has the strongest magnetic field?


Can we live without a magnetic field?

Without it, life on Earth would be over very quickly. … The Earth’s magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds.

Does Mars have magnetic fields?

Facts about Mars’ magnetic field

Unlike the Earth, Mars has no inner dynamo to create a major global magnetic field. This, however, does not mean that Mars does not have a magnetosphere; simply that it is less extensive than that of the Earth. … The outer boundary of the planet’s magnetic field is called ‘bow shock’.

Does Earth have a magnetic field?

In a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.
