Abstract :
A magnetic fluid full of uniform inert spheres behaves like a liquid crystal when it is magnetised. The spheres form long chains, which arrange themselves into a triangular lattice. For a conducting liquid, resistance across the chains can be >30 times that along their length. This active device can be large and self repairing.
