Three dimensional alignment of magnetic particles

Abstract

In this article, novel magnetic particle alignment methods, which we refer to as dynamic alignment, are presented. In the process of a dynamic alignment, the magnetic field direction is periodically changed while the particle orientation is captured in epoxy resin. Depending on the manner of the variation of the magnetic field, particles can be aligned in various patterns. By employing the dynamic alignment methods described in this article, the alignment of magnetic particles can be achieved such that particles are aligned along all three crystalline axes.
