What is a planetary magnetic field?
Quick Answer
A planetary magnetic field is the region of magnetic influence generated by a planet’s interior or electrical currents.
The Full Story
Planetary magnetic fields can deflect charged particles and create magnetospheres. Earth’s field is generated by the motion of molten iron in its outer core, acting like a natural dynamo. Jupiter’s magnetic field is the strongest of any planet in the Solar System, while Mercury also has a weak global field. Venus and Mars lack strong global magnetic fields today, which affects how their atmospheres interact with the solar wind.
