Influence of electro-magnetic boundary conditions onto the onset of dynamo action in laboratory experiments

Time: October 29, 2003, 3:00 pm
Place: Building 19, Room 19.415

We study the onset of dynamo action of the Riga and Karlsruhe experiments with the addition of an external wall, the electro-magnetic properties of which being 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 ferro-fluid in motion.
