The dipole magnetic field created by this permanent moment has a strength of 719 ± 2 nT at Ganymede's equator, [23] which should be compared with the Jovian magnetic field at the distance of Ganymede—about 120 nT. [95] The equatorial field of Ganymede is directed against the Jovian field, meaning reconnection is possible. The intrinsic field ...

The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with
Europa is similar in size to Earth’s Moon, while Ganymede is the largest moon in the whole Solar System. PhD student Oliver King, from the University of Leicester’s School of Physics and ...
(Ice has less tensile strength than rock, and is deformed at lower pressures and temperatures than rock.) The evidence is perhaps strongest for Ganymede, which has a magnetic field that indicates the fluid movement of electrically conducting material in its interior, though whether that fluid is a metallic core or a subsurface ocean is unknown ...
One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts. NASA's Galileo ' s measurements suggest that large moons can have magnetic fields; it found Ganymede has its own magnetosphere, even though its mass is only 2.5% of Earth's. [18]
Vasil and his team developed new models of the interaction between the sun’s magnetic field and the flow of plasma, which varies at different latitudes during an 11-year cycle.
The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is. For example, Earth possesses an enormous magnetic moment, however we are very distant from its center and experience only a tiny magnetic flux density (measured in tesla ) on its surface.
