Distribution p(k) as a function of the normalized wavevector k/k₀, calculated for different values of the parameters μ and n_max of the equilibrium magnetic field B⁽⁰⁾. The quantity p(k) is proportional to the fluctuation spectrum per unit volume ϵ(k) in the homogeneous region. A power law with slope −α = −2.3 is also shown for comparison.
