Abstract

We investigate the kinematic and dynamic dynamos that result when the magnetic field is assumed to be spatially periodic on a scale twice that of the periodicity of the underlying driving velocity, the "CP flow" of Galloway and Proctor (1992). In the kinematic regime four distinct modes are possible; all appear to exhibit fast dynamo action. In the nonlinear regime mode coupling may occur and different saturated states are possible for the same parameter values.
