The universal growth of magnetic energy during the nonlinear phase of subsonic and supersonic small-scale dynamos

Neco Kriel, James R. Beattie, Mark R. Krumholz +2

Small-scale dynamos (SSDs) amplify magnetic fields in turbulent plasmas. Theory predicts nonlinear magnetic energy growth $E_{\mathrm{mag}}\propto t^{p_{\mathrm{nl}}}$, but this scali…
