At sufficiently large magnetic Reynolds numbers turbulent hydromagnetic flows can exhibit self-induced dynamo action. There are many examples in astrophysics where this happens, and there is now enhanced activity in trying to establish dynamo action in laboratory experiments. Meanwhile, numerical simulations have contributed a great deal to understanding this phenomenon. In my talk I will discuss various simulations displaying dynamo action. Particular attention will be given to the generation of ordered, large scale magnetic fields. This phenomenon is related to the existence of an inverse cascade in hydromagnetic turbulence.
