Comparison between the magnetic (solid) and kinetic (dotted) energy spectra . The slanted dash-triple-dot line represents a power law with exponent −3.23. The vertical dotted lines mark the boundaries of the observational domain, while the vertical dash-dotted line marks the 2 Mm scale, for reference. There is approximate equipartition between the magnetic and kinetic energy densities over the range 0.3–2.0 Mm, and both spectra exhibit power law behavior for scales smaller than about 1.2 Mm.
