Abstract�� Using three-dimension model, the hybrid particle in cell method was used to simulate the interaction between the inflated magnetic field and solar wind. The interaction between solar wind particles and dipole magnetic field produced by coil was studied after the plasma injecting into the dipole magnetic field. The changing of solar wind and magnetic field was compared when the plasma was injected with different velocity. It is shown that the bow shock like-structure caused by the interaction between solar wind and dipole magnetic field appears at the area where the magnetic pressure and the dynamic solar wind pressure balance each other. The magnetic field inflates when high-energy density plasma was injected into the dipole magnetic field, then the magnetic field expels the solar wind particles outward. The bow shock like-structure changes and it increases the cross area with the solar wind. It is shown that the bigger the velocity of injected plasma, the more clear the magnetic field inflation and the stronger the interaction with solar wind.
