On Kinematic Generation of the Magnetic Modes of Bloch Type

摘要: Kinematic generation of electrically conductive fluid by space-periodic flow is considered. The generated magnetic modes have a form product three-dimensional field having the same spatial periodicity and Fourier harmonic whose wave vector q an arbitrary constant. We present examples computation associated with maximum (over q) growth rates for generic velocity where α-effect parity-invariant lacking featuring negative eddy diffusivity. It shown that over are characterized weak separation scales, and, therefore, neither two noted effects can be regarded as main mechanism responsible their generation.
