In a method to control the movement of an endoscopy capsule in a hollow organ of a patient using a magnet system, a movement signal of the endoscopy capsule in the hollow organ is detected, that represents the time curve of the spatial position. The movement signal is evaluated to identify a periodic signal component thereof, and the frequency of this periodic signal component is identified. The magnet system is operated to exert a force on the endoscopy capsule in the hollow organ that is periodic with the frequency of the periodic signal component, and that is directed opposite to the movement signal.
