Abstract

Since the turn of the century, experiments have produced laboratory fluid dynamos that enable a study of the effect in controlled conditions. We review here magnetic induction processes that are believed to underlie dynamo action, and we present results of these dynamo experiments. In particular, we detail progress that have been made through the study of von Kármán flows, using gallium or sodium as working fluids.
