This book addresses and reviews many of the still little understood questions related to the processes underlying planetary magnetic fields and their interaction with the solar wind.

«While WASP - 12b is far too hot to support life, being able to detect planetary magnetic fields will help with our understanding of and identifying the habitable zones around exoplanets,» says Joseph Llama, a Ph.D. student on Vidotto's team.

Scientists think a dynamo — a rotating, convecting, electrically conducting fluid in a planet's outer core — is the mechanism for generating the planetary magnetic fields.

On Mars, there is no organized planetary magnetic field to guide the particles north and south — so they can go anywhere.
