## Abstract The dynamo effect is numerically simulated for a model of the Karlsruhe dynamo. A flow periodic in two directions and independent of the third coordinate is considered. Each periodicity cell contains four helical vortices. The novelty of the model is that it includes cylindrical walls e
Convection driven by horizontal temperatures gradients in an electrically conducting, viscous, Boussinesq fluid has been studied on a computer. Results of numerical experimentswith a Grashof number of 1 are presented and compared with linear theory. Weak magnetic fields are distorted and concentrate
