What is the most advantageous magnetic attitude control torquer for reducing angular rates of a PocketQube? To answer this question several magnetorquer concepts are explored and two concepts are built. In addition, a method to test these magnetorquers is developed. An Air-core magnetorquer system and a magnetorquer embedded in a PCB are designed, built and tested. By building and testing the designs also possible construction issues related to a concept can be found, which are not evident when only designing the magnetorquers. The Air-core magnetorquers also serves as a prototype for the magnetorquer for Delfi-PQ, the satellite to be launched by Delft University of Technology. After testing two concepts are then compared with each other and also with other concepts such as a ferromagnetic torque rod.
