Power spectra of magnetic energy for each of the components of the magnetic field calculated at the final time for the simulations L1-WN (top left), L1-WN-NN (top right), and L1-WN-NN-B (bottom left), and P-WN-NN (bottom right). We note that the simulation P-WN-NN has no magnetic energy in the x and z directions. Solid lines are individual components of the magnetic energy, (blue), (red), (orange). Dashed lines are for the in-plane component, (green), and the total energy, (black).
