The response of a shock wave in a Faraday-type MHD generator to small-amplitude pressure disturbances introduced downstream of the shock wave is analyzed with the method of small perturbations. The subsequent shock wave motion is classified as a stable oscillation about the initial steady flow shock position and an unstable oscillation where the shock wave moves upstream of the MHD channel, depending on interaction parameter, channel cross section and load parameter in the upstream of the shock wave. In the case of unstable condition, the Faraday-type MHD generator has a hysteresial characteristics such as the jump behavior of shock wave position and power output.
