Abstract: We show that the magnetic kink waves generated by the motions of the photospheric footpoints of the coronal flux tubes can supply adequate energy for heating the quiet corona. We model the solar corona as two-layer isothermal atmosphere, with the lower layer having chromospheric thickness and the temperature and the upper layer having coronal temperature.
