ScopePaleomagnetism and paleointensity are essential tools that are useful in investigating the history of Earth's lithosphere, deep interior, and environment. Likewise, geomagnetic observations, modeling, and dynamo simulations are also important tools that help elucidate the dynamics of the Earth's magnetic field and the core. Beyond Earth, studies on extracting ancient magnetic fields recorded by extraterrestrial materials are increasing, which are improving our understanding of the evolution of other planetary bodies in addition to the solar system. Here, we invite contributions in the broad spectrum of paleomagnetic research with special emphasis on the "Study of the Earth's Deep Interior" (SEDI) that illustrate modern advances and highlight further work to better understand the dynamics and evolution of Earth and other planetary bodies. Topics of interest include (but are not limited to): geomagnetic jerks, secular variation, excursions and reversals, magnetic field modeling and dynamo simulations, geometry of the geomagnetic field, paleointensity and evolution of the core and core-mantle boundary, polarity reversal frequency through time, magnetic shielding and solar radiation effects, evolution of magnetotactic bacteria and magnetic field, in addition to planetary magnetic fields and evolution of solar system.
