Liquid metal experiments on the generation and action of cosmic magnetic fields

The lecture starts with an introduction about the various interactions between the flows of electrically conducting fluids with magnetic fields, including the homogeneous dynamo effect and the celebrated magnetorotational instability in accretion disks. It continuous with an overview about previous liquid metal experiments dedicated to the laboratory demonstration of both effects, and concludes with an outlook on the large-sale liquid sodium experiments that are planned in the framework of the DRESDYN project.
