This movie depicts the influences of field gradients on a collection of vertical rotating
magnetic particle chains forming micro-stirrers.

This movie depicts the generation of a swarm of rotating magnetic particle chains actuated by a vertical clockwise rotating magnetic field (30 Hz, 30 mT).

This movie depicts the direction control of the swarm by exposing the magnetic particles with a counter-clockwise rotating magnetic field.

This movie depicts the different regimes of the swarming particles.

This movie shows the triaxial control of the swarm of rotating magnetic particle chains.

This movie depicts the induced fluid flow actuated by a swarm of magnetic particle chains.

This movie depicts mixing using a swarm of magnetic particles.
