Assuming the magnetorquer and the field generating electronics are both rigidly fixed to the spacecraft cube. Reference to any supporting papers/articles would be great. Thanks.
Would the residual field affect the performance of the magnetorquer due to generation of back emf. To cancel which, more current must be passed to get the same torque (in case polarity of emf is opposing) and less current in the other direction where emf polarity is favorable. Constant external field assumed.
