Background
-Magnetohydrodynamics (MHD)Turbulence: Magneto – magnetic fluid
hydro - Liquid
dynamics - movement
-MHD deals with dynamics of electrically conducting fluids.
-MHD Turbulence is observed when the Reynolds number of magnetofluid is large.

Summary -Generally, the fluctuation of magnetic energy decreases with the increase of radial distance. On the other hand the correlation length increases which we can see in undriven models.
-There is a slight increase of magnetic energy density in driven model which is because of the source term.
-The correlation length in the case of pickup ion driven models decreases with increase of radial distance which is different than other two models.
- Most of the systems are in unsteady state first and as the time passes it is getting to steady state which we can see in the result.
