Abstract
Standard magnetohydrodynamic theories, such as the mean field dynamo theory, have been criticized when the backreaction of the magnetic field on turbulent motions is neglected. For the dynamo, this backreaction has been argued to suppress the turbulent motions required for optimal mean field production. Here it is suggested that if the magnetic field is spatially intermittent, for example, residing in flux tubes, the backreaction on turbulent flows may be significantly reduced.Keywords
