Zusammenfassung:The present invention relates to a device for generating a variable angular momentum or torque, which has a container (1) partially filled with a magnetizable fluid (2) and a device for generating one or several rotating or wandering magnetic fields, with which the magnetizable fluid (2) in the container (1) can be made to continuously move on a closed orbit. The device for generating the rotating or wandering magnetic fields has several electric coils (4), whose coil axes lie in the orbital plane. This structure makes it possible to generate a variable angular momentum without mechanical moved parts or the necessity of external magnetic fields. For example, the device enables a simple and cost-effective spacecraft attitude control.
