Caption:
Magnetic field perturbations, $\delta B/B_0$, for different time steps and for the scenario of a vertical magnetic field. The magneto-acoustic wave propagates from the source (piston) located at (x; z) = (1000; -750) km. The horizontal line shows the equipartition level, where the sound speed equals the Alfven speed, $c_\mathrm{s}=c_\mathrm{A}$. The vertical lines represent magnetic field lines.

Caption:
Evolution of the velocity perturbation scaled with the square root of the density, $ \rho^{1/2} \delta|v|$, for the scenario of a tilted magnetic field with  $\theta$= 30$^°$. The horizontal line shows the equipartition level, where the sound speed equals the Alfven speed, $c_\mathrm{s} = c_\mathrm{A}$. The tilted lines represent magnetic fi eld lines.
