A magnetic field is a vector field, but if it is expressed in Cartesian components X, Y, Z, each component is the derivative of the same scalar function called the magnetic potential. Analyses of the Earth's magnetic field use a modified version of the usual spherical harmonics that differ by a multiplicative factor.
These magnetic fields are a hundred million times stronger than any man-made magnet, [11] and about a trillion times more powerful than the field surrounding Earth. [12] Earth has a geomagnetic field of 30–60 microteslas, and a neodymium-based, rare-earth magnet has a field of about 1.25 tesla, with a magnetic energy density of 4.0 × 10 5 J ...
George R. R. Martin set the Ice and Fire story in an alternative world to Earth, a "secondary world". [S 3] Martin has also suggested that the world may be larger than the real world planet Earth. [S 4] The Ice and Fire narrative is set in a post-magic world where people no longer believe in supernatural things such as the Others.
As the largest planet in our solar system, Jupiter has a magnetic field 20,000 times stronger than Earth’s, according to NASA. The magnetic field traps charged particles and accelerates them to ...
In 2014, a magnetic field around HD 209458 b was inferred from the way hydrogen was evaporating from the planet. [20] [21] In 2019, the strength of the surface magnetic fields of 4 hot Jupiters were estimated and ranged between 20 and 120 gauss compared to Jupiter's surface magnetic field of 4.3 gauss.
Title Planet Star Data Notes Most massive The most massive planet is difficult to define due to the blurry line between planets and brown dwarfs.If the borderline is defined as the deuterium fusion threshold (roughly 13 M J at solar metallicity [21] [b]), the most massive planets are those with true mass closest to that cutoff; if planets and brown dwarfs are differentiated based on formation ...

The spacecraft encountered magnetic "tornadoes"—twisted bundles of magnetic fields connecting the planetary magnetic field to interplanetary space—that were up to 800 km wide or a third of the radius of the planet. These twisted magnetic flux tubes, technically known as flux transfer events, form open windows in the planet's magnetic shield ...
