Multiscale non-helical dynamos
Description:  In this talk a short introduction to the magnetic dynamo theory (explaining how magnetic fields can be produced by flows of an electrically conducting fluid) as well as recent advances made by the speaker and his collaborators will be presented. Generation of large-scale magnetic field by zero-helicity flows will be discussed in detail using a rigorous mathematical approach (multiscale analysis). The following optimization problem will also be addressed -- Which flow is the most favorable to magnetic field generation.
