By means of small magnetic field ac susceptibility measurement at 10 kHz we found that the real and imaginary parts of ceramic YBa2Cu3O_ x susceptibility in presence of the external low frequency field close to 0.1 Hz exhibit frequency dependence. The wide maximum of hysteresis losses and \colorblack the exponential dependence of the \colorblack effectiveness of flux penetration with increasing of external field frequency were obtained. We observed a nonlinear dynamic magnetic response in presence dc field and we suggest that this behavior is due to the dynamic and static Josephson vortex-vortex interaction.
