Abstract

Understanding the origin and dynamics of the Earth's magnetic field is the primary goal of this research. Laboratory experiments conducted in liquid sodium are used to reach Earth-like parameters to study fluid flow-magnetic field interactions. Understanding the role of turbulence, global rotation, and magnetic forces on the Earth's core are primary issues addressed in the research. This project includes working in collaboration with researchers involved in simulations of the geodynamo, in order to assist in benchmarking computational models. This research also seeks to broaden its impact through the training of young scientists, and through public outreach activities. Undergraduate and graduate researchers play a critical part in the project scientific activities. The mentoring of future scientists is an important part in this experimental research. Through lectures, participation in television documentaries, and by articles in scientific news magazines, this project seeks to improve the public appreciation and knowledge of science relating to the geodynamo and geophysics experiments.Lathrop
