Abstract

We study the onset of dynamo action of the Riga and Karlsruhe experiments with the addition of an external wall, the electromagnetic properties of which are different from those of the fluid in motion. We consider a wall of different thickness, conductivity, and permeability. We also consider the case of a ferrofluid in motion.
