Abstract
The aim of this review is to describe some aspects of the dynamic properties of magnetic multiparticle systems in the micrometer range. These particles include monodisperse magnetic microspheres, and magnetic holes, i.e. nonmagnetic particles dispersed in ferrofluids.
The complementary use of analogue simulations and computer simulations to explore the dynamic properties is demonstrated.
The ability to describe the complex dynamics of magnetic holes in quantitative symbolic dynamic terms using the notion of knot- and braid theory will be discussed. In particular, statistical analysis of braid words, diffusion, memory effects and correlations for the complex dynamics is illustrated.

The reference frame rotating in unison with the magnetic field is not the only one in which the N-strand structures plaited by the magnetic holes can be seen as periodic braids. In another reference frame of this kind one of the axes, x”, rotates together with the long axis of the cluster formed by the magnetic holes.
