Mean orientation of the pinned swimmer in channels of increasing width. The magnetic field is aligned along the main axis of the channel and the numbers indicate the width of the channel in mm. Magnetic field parameters: frequency 40 Hz, amplitude 1.5 mT. Swimmer’s mean orientation was determined by analysing SI Movie 5 and the flow speeds are shown in Fig. 7. The direction of flow is downwards.
