Theoretical Methods for Studying Distance and Frequency Scaling for AC Magnetic Fields in Satellite Missions

In this paper, magnetic source models based on physical phenomena are introduced for the purpose of studying ac magnetic cleanliness. More explicitly, a theoretical analysis of the magnetic behavior of current loops has been carried out with respect to several parameters, i.e., shape, area, frequency, and current type. The parameters were studied individually, resulting in different power laws of the magnetic field. The present research focuses on frequency and distance scaling of the magnetic field, resulting in indicative power laws for several magnetic loop types. This approach can form a basis to identify the parameters of the magnetic loops inside equipment under test by measuring the magnetic field falloff.
