## Abstract We study the evolution of growth and decay laws for the magnetic field coherence length __ΞΎ__, energy __E__~M~ and magnetic helicity __H__ in freely decaying 3D MHD turbulence. We show that with certain assumptions, self‐similarity of the magnetic power spectrum alone implies that __ΞΎ__
