<p class="MsoNormal"><span lang="EN-GB">Magnetic fields are fundamental features of Earth and numerous other planetary bodies. Studying them offers valuable insights into the internal and external dynamics as well as the evolution of planets. Magnetic fields
exhibit variations across a wide range of temporal and spatial scales, from the present to the distant past, and from regional to global scales, respectively. Understanding the secular variation and the processes driving these changes is crucial for predicting
the future evolution of planetary magnetic systems. Their study employs various methods, including observations, data-based models, numerical simulations, and theoretical studies. Observations encompass magnetic data measured on the ground or by satellites,
as well as paleomagnetic data obtained from geological archives such as volcanic rocks, archeological artefacts, sediments, and speleothems. On the other hand, models and simulations make measured guesses of the fields and the processes happening both inside
and outside the planetary bodies. This session covers all types of observations, simulations, and methods for studying planetary magnetic fields and their evolution, with a particular focus on their multi-scale nature.<o:p></o:p></span></p>
