    Yes, that makes sense.  Do you know what is the "major" magnetic material
    (in terms of quantity and magnetic field strength.  Aluminum is a common
    material used in building satellites, but it is only a paramagnetic
    material) for Starshine?
    When the typical satellite has its spin rate gradually reduced, is this
    primary from the atmosphere, or the Earth's magnetic field?
