The process of plasmoid formation and evolution in the magnetotail is investigated using two three-dimensional resistive MHD simulations of a magnetotail configuration with a far-tail portion included. The dynamic evolution consists of several characteristic stages: (1) a weak diffusion during which the distant B(z) = 0 line moves tailward and finally disappears; (2) the formation and growth of a plasmoid body through reconnection in the near-earth region; and (3) the separation of the plasmoid. The total force acting on the plasmoid body is dominated by pressure gradients in the early stage and by the Lorentz force at later times, when the plasmoid separates from earth. The most important cause of growth and separation of plasmoid is the accumulation of newly reconnected field lines carrying plasma.
