Abstract
Recent developments in kinematic dynamo theory are described. Attention is restricted to the case of large magnetic Reynolds number dynamos. The nature of the "slow" Braginsky dynamo, which operates on the magnetic diffusive timescale, is outlined. The possible existence of "fast" dynamos, which grow on the time scale of the convective motions is discussed. Only steady flow is considered but the case of particle paths confined to stream surfaces is carefully distinguished from the case with chaotic particle paths. The underlying theme is that of flux expulsion with magnetic field confined to ropes and sheets.
