The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...
The radius of the outer core is about half of the radius of the Earth. If the field at the core-mantle boundary is fit to spherical harmonics, the dipole part is smaller by a factor of about 8 at the surface, the quadrupole part by a factor of 16, and so on. Thus, only the components with large wavelengths can be noticeable at the surface.
Generated by the churning molten metals in Earth’s core, the magnetosphere shields the planet from harmful solar radiation and keeps solar winds from stripping away Earth’s atmosphere.
The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [3] in the Earth's outer core. [4] In 2001, it was determined by the Geological Survey of Canada to lie west of Ellesmere Island in northern Canada at 81°18′N 110°48′W / 81.300°N 110.800°W / 81.300; -110.800 ( Magnetic North Pole
Jupiter radiation. Jupiter's magnetosphere is a complex structure comprising a bow shock, magnetosheath, magnetopause, magnetotail, magnetodisk, and other components.The magnetic field around Jupiter emanates from a number of different sources, including fluid circulation at the planet's core (the internal field), electrical currents in the plasma surrounding Jupiter and the currents flowing ...
Shape changes in the core could hold clues about the forces deep inside Earth that power our magnetosphere, the invisible lines of magnetic energy that protect our planet from solar weather and ...
Surrounding Jupiter's magnetosphere is a magnetopause, located at the inner edge of a magnetosheath—a region between it and the bow shock. The solar wind interacts with these regions, elongating the magnetosphere on Jupiter's lee side and extending it outward until it nearly reaches the orbit of Saturn. The four largest moons of Jupiter all ...
The magnetosphere contains charged particles that are trapped from the stellar wind, which then move along these field lines. As the star rotates, the magnetosphere rotates with it, dragging along the charged particles. [13] As stars emit matter with a stellar wind from the photosphere, the magnetosphere creates a torque on the ejected matter.
