A bifurcation from the static state to the dynamic state in the asymmetric plasma divided by the magnetic filter (MF) is studied by an one-dimensional particle simulation. A low temperature and low density subplasma is in contact with a high temperature and high density main plasma at the MF. In the dynamic state, autonomous oscillation of the electrostatic potential in the subplasma is observed along with the transit of the shock wave structure [K. Ohi, H. Naitou, Y. Tauchi, and O. Fukumasa, Phys. Plasmas 8,23(2001)]. By changing the control parameter of B_0 very slowly, the existence of the hysteresis in the relation of △φ_s versus B_0 is verified. Here B_0 is the strength of the magnetic field at the center of the MF and △φ_s is twice the amplitude of the self-sustained potential oscillation in the subplasma.
