Abstract

A magnetic chain, self-assembling from magnetic particles, may act as an intelligent micro-stirrer, inducing chaotic mixing in a well-chosen rotating magnetic field. We investigate this using a 2D circular cavity with magnetic particles. The motion of the chain is dependent on the Mason number. At a lower Mason number, the chain rotates like a rigid body. We observe break-up of the chain at a certain range of the Mason number. The detached chains either assemble into a single chain again or remain as separate chains depending on the Mason number. The alternating break-up and reformation of the chain lead to better mixing.
