What to expect from next generation liquid metal experiments on dynamo action and magnetorotational instability?

After a short summary of the achievements made in liquid metal experiment during the last seven years, we try to identify some important points which should be addressed by next generation experiments. These include the role of rotation and precession, the role of large scale and small scale fluctuations on the dynamo threshold, the occurrence of field reversals in highly supercritical states and further studies of the magnetorotational instability in cylindrical, spherical and oblate geometries.
