N2 - Particle-based magnetically actuated microswimmers have potential to be used as microrobotic tools for biomedical applications. In this paper, we report the dynamic swimming behaviors of a magnetic microswimmer near a solid surface. This microswimmer consists of three paramagnetic microparticles and is actuated using a rotating magnetic field. The microswimmer exhibits simple rotation and propulsion with varied dynamic poses by tuning the input frequency of applied field. When the input frequency is less than 8 Hz, the microswimmer performs simple rotation and has no translational displacement. When subjected to higher input frequency (8-15 Hz), it performs propulsion, resulting in dynamic swimming behaviors. Moreover, our results indicate that higher swimming velocity is realized if the microswimmer swims near a solid surface because of the induced pressure difference in surrounding fluid of the microagent.
