Abstract: Differential operator elimination method was applied to solve the Maxwell's system of partial differential equations obtain to the general expressions of transverse permeability for magnetic ribbons. The expressions of transverse permeability for magnetic ribbons were found out in driving current full frequency section with the Landau-Lifshite equation. The results show that under the alternating magnetization the transverse permeability of ribbons relate to external magnetic field and driver electric current frequency，and has be orientation-related relativity as well.
