In this paper, we describe mode-to-mode energy transfers and energy fluxes of MHD turbulence. These energy transfers are very useful for understanding turbulence dynamics, as well as for applications, such as dynamo. We illustrate how the energy fluxes provide valuable insights into the mechanism of growth of large-scale magnetic energy in dynamo. Tables 2, Figs 5, Refs 14.
