The formula relating the planetary magnetic fields to the parameters of rotation and precession of the planets and to the density and conductivity of their liquid cores has been proposed basing on the similarity

In contrast, internal sources include remanent magnetization in crustal rocks on Mars, Earth, and the Moon or self-sustaining dynamos in the deep interiors of planets. This latter process will be the main focus of this chapter. 1.2 Spatial Characteristics of Dynamo-Generated Fields Dynamo-generated...
“If there was a magnetic field on this moon that we’ve considered geologically torpid for so long, it might mean something for global magnetic fields on other planets,” saysGeorgiana Kramerat the Lunar and Planetary Institute in Texas. Law of attraction Right now, we don’t know...
Magnetic fields on other planets Earth is not the only planet in the solar system to possess a magnetic field.Jupiter,Saturn,UranusandNeptuneall exhibit magnetic fields far stronger than Earth's, according toUnion University, though the underlying mechanisms driving these magnetic fields are not yet...
Understanding properties of stellar magnetic fields in these stars finds a broad application in astrophysics, including theory of stellar dynamos and environment conditions around planets that may be orbiting these stars. Most stars with convective envelopes follow a rotation–activity relationship where ...
Some planets and many stars have magnetic fields that are generated by a convection-driven dynamo process. Stellar fields, known from their effect on the emitted light, are often 1,000 times stronger than that of Earth, so if the dynamo mechanism is simi
particularly for the search for extraterrestrial life. “Stars experiencing this enhanced magnetism are likely going to be battering their planets with high-energy radiation,“ Cao said. “This effect is predicted to last for billions of years on some stars, so it’s important to understand what...
worlds across time: “The question I wanted to ask is, around these small stars, where people are going to look for planets, are these planets going to be roasted by gravitational tides?” He was curious, too, about the effect of tidal heating on magnetic fields across long periods of ...
