 Context examples 

Magnetic fields are produced by what are known as dynamos — convective motion of electrically conducting fluid inside planets.

(Juno Peers Inside a Giant, NASA)

It has been a bedrock tenet of geophysics that Earth's liquid outer core has always been the source of the dynamo that generates its magnetic field.

(Earth's mantle, not its core, may have generated planet's early magnetic field, National Science Foundation)

The observations made by Juno's magnetometers will also add to our understanding of Earth's dynamo, the source of our planet's magnetic field, which lies deep beneath a magnetized layer of rocks and iron.
