Conservational model for formation process of magnetic insulation

For the plane magnetically insulated transmission line(MITL), coaxial MITL, and cone MITL, the analytical expression of initial current is derived according to the conservation of magnetic flux, and the analytical expression of initial voltage is derived according to the conservation of charge. Then, the relations of the initial current and voltage with the final steady state current and voltage are numerically calculated. The results of simulation agree well with the results of two-dimensional particle-in-cell(PIC) simulation.
