The Pioneer Saturn vector helium magnetometer has detected a bow shock and magnetopause at Saturn and has provided an accurate characterization of the planetary field. Like the Earth's, Saturn's field is a magnetic dipole. The degree of tilt would also resolve the question of how long a day is on Saturn. This means the field is exactly in line with the planet's axis. However, direct measurement of the field’s rotation was difficult because the field is highly symmetrical around the rotational axis. The equatorial surface field is 0.20 gauss, a factor of 3 to 5 times smaller than anticipated on the basis of attempted scalings from Earth and Jupiter. Saturn's magnetic field interacts with the solar wind and creates ultraviolet auroras. Saturn's field is unique in that it is perfectly symmetrical, unlike any other known planet. The core is heated by the rapid rotation, which is equivalent to 10 Earth hours, and the gravity pulling liquid helium towards the center. Saturn has a natural magnetic field that is weaker than Jupiter's. The magnetic field of Saturn, which is also a gas giant, is generated by metallic hydrogen that covers a rocky core. Credit: NASA.

How long is a day on Saturn? Further, the Jovian magnetic field has much higher complexity than that of the Earth, with some aspects of Jupiter's fields having no Earthly counterpart. Saturn. The Earth has a strong magnetic field, but Jupiter's magnetic field at the tops of its clouds is 10 times stronger than that of the Earth.

The collapse of the magnetotail appears to kick off a process that causes the hot plasma bursts, which in turn inflate the magnetic field in the inner magnetosphere. Yes, Saturn has a magnetic field that is produced by electric currents. The force of the solar wind stretches the magnetic field of the side of Saturn facing away from the sun into a so-called magnetotail. I guess that also means it is going to be a real challenge for scientists to enter Saturn in the future.
