There is presently an international effort to reproduce the dynamo effect on a laboratory scale. Two experiments (one in Karlsruhe and another one in Riga) have already been successful in generating a self‐excited magnetic field. Other experiments (in Cadarache, Madison, and Maryland) have not reached the critical magnetic Reynolds number yet but have been useful in exploring the approach to self‐excitation. This paper reviews the motivation behind the different experiments and the first results which have been obtained.
