Systematic study is done on problems of resistance and flux losses in helical magnetic flux compression generator(MFCG) based on current equation and magnetic diffusion equation. The program MFCG-Ⅳ is extended by considering contact resistance model, and ohmic resistance model based on skin depth and neighboring interaction model. Using the experimental parameters of Texas Tech University(TTU), comparable numerical results with the experimental ones are derived, which can depict the physical phenomena.
