Abstract
The aim of this study is to determine decay of magnetic field fluctuations in MHD turbulence for four-point correlation in a rotating system before the final period. Two, three and four point correlation equations have been obtained and the set of correlation equations is made determinate by neglecting the quintuple correlations in comparison to the third and fourth order correlation terms. The correlation equations are converted to spectral form by taking their Fourier-transforms. Finally, integrating the energy spectrum over all wave numbers. The energy decay of magnetic field fluctuations for four-point correlations in a rotating system is obtained and is shown graphically in the text.

Summary
Magneto-Hydrodynamics is the science which deals with the motion of highly conducting fluids in the presence of a magnetic field. Islam and Sarker (2001b) studied the decay of dusty fluid MHD turbulence before the final period in a rotating system.
