Presented by Dr. Peter Driscoll: Staff Scientist, Department of Terrestrial Magnetism, Carnegie Institution for Science

Earth's magnetic field is generated by convective motion in the liquid iron outer core, commonly referred to as the #geodynamo. The magnetic field has been protecting Earth from harmful charged particles for at least the last 2.5 billion years, and possibly longer.

In this talk, Dr. Driscoll will discuss the physical mechanisms that produce the geomagnetic field, conduct a brief survey of planetary magnetism, and explore Earth’s rich paleomagnetic history preserved in ancient rocks, including polarity reversals, superchrons, paleointensity, and the impact of the solidification of the inner core. He will highlight the pioneering contributions made by the Department of Terrestrial Magnetism on early studies of geomagnetism.
