Missions requiring magnetically clean spacecraft seem to experience magnetic fields due to thermoelectric currents. At the interface of different electrically conductive materials and due to inhomogenities even inside single materials temperature differences cause differences in electron densities and therefore differences of electric potential. These potential differences drive electric currents, which are sources of magnetic field emissions. The phenomena are known to exist, and need to be studied from a multi-disciplinary perspective encompassing thermal, electric, magnetic and material aspects with special attention to possible mitigations.Understanding the physical roots of the perturbation and modeling the phenomena will improve the data exploitations for the actual and future magnetic missions.
