Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating from the sun can interact directly with the moon, producing eddy currents that generate an induced magnetic field. These induced fields can be modeled by assuming a conductivity structure for the lunar interior. COMSOL Multiphysics® is used to solve the full time domain response of models of the moon for varying electrical conductivities. Ultimately, we desire a full time-dependent solution for arbitrary signal inputs, such that the input and induced fields measured by the ongoing ARTEMIS lunar mission can be compared to our model.
