Description
We performed one-dimensional force-free magnetodynamic numerical simulations of the propagation of Alfven waves along magnetic field lines around a spinning black hole hole to investigate the dynamic process of wave propagation and energy transport with Alfven waves. We considered axisymmetric and stationary magnetosphere and perturbed the background magnetosphere to obtain the linear wave equation for the Alfven wave mode. As shown by the previous study \citep{koide22} with the BTZ coordinates, the Alf\'{e}n wave induces the fast wave. Considering the additional fast magnetosonic wave induced by the Alfven wave, the energy conservation is confirmed.
