    The strong, global, and ever-changing magnetic field is one of the fundamental characteristic features of the Earth. In contrast, neither Venus nor Mars currently has a global magnetic field despite being otherwise relatively similar terrestrial planets. This talk will cover topics such as how the Earth’s magnetic field is generated deep within its core, possible reasons why Venus and Mars don’t have a magnetic field, and how the lack or presence of a magnetic field matters for the long-term habitability of a planet.

    Jon Mound is associate professor of geophysics in the School of Earth and Environment at Leeds University. He researches the Deep Earth, including the dynamics of the core-mantle system.
