Dr Jon Mound (Leeds University) will speak on The Earth’s Core and Its Magnetic Field
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.

Cafe Sci Leeds was set up to encourage understanding and debate about topical scientific research and issues in an informal setting. Speakers are invited to present a short talk on an area of science in which they have been involved which is then followed by questions and comments.
