 note = {0000-0003-2691-5068, The electric field parallel to the magnetic field in nonlinear magnetosonic waves in three component plasmas (two-ion-species plasma and electron-positron-ion plasma) is theoretically studied based on a three-fluid model. In a two-ion-species plasma, a magnetosonic mode has two
branches, high-frequency mode and low-frequency mode. The parallel electric field E|| and its integral along the magnetic field, F = - ∫ E|| ds, in the two modes propagating quasiperpendicular to the magnetic field are derived as functions of the wave amplitude and the density ratio and
cyclotron frequency ratio of the two ion species. The theory shows that the magnitude of F in the high-frequency-mode pulse is much greater than that in the low-frequency-mode pulse. Theoretical expressions for E|| and F in nonlinear magnetosonic pulses in an electron-positronion
plasma are also obtained under the assumption that the wave amplitudes are in the range of (me/mi)1/2 < ∈ < 1, where me / mi is the electron to ion mass ratio.},
