From: Characterizing dynamic behaviors of three-particle paramagnetic microswimmer near a solid surface

Velocity of the microswimmer against frequency. Velocity of the microswimmer against frequency of the applied magnetic field. Rotation axis is perpendicular to the solid surface (\(\alpha =0^{\circ }\)). Blue and black lines are the velocity in bottom space (0–20 \(\upmu \hbox {m}\) above the substrate) and upper space (20–40 \(\upmu \hbox {m}\) above the substrate), respectively. Error bars denote the standard errors from observation time that is used to calculate velocity
