All Magnetic Active Matter

We will describe a system of artificial nanoswimmers that are powered by small external magnetic fields, and whose direction of motion is governed by orientational diffusion and interactions with each other. This all magnetic active matter can be seamlessly converted into a driven system and provide a promising platform to test and investigate various collective phenomena. In particular, we will describe experiments to study this novel system under strong confinement that is different from typical hard wall interactions.
