内容記述 | The electric field parallel to the magnetic field, E_||, in nonlinear magnetosonic waves is studied theoretically and numerically. In the calculation of E_|| based on the conventional reductive perturbation method, the terms related to the magnetic pressure cancel, and E_|| is proportional to the electron temperature T_e. With a modified perturbation scheme assuming that the wave amplitude is in the range (m_e/m_i)^1/2<ε<1, an expression for E_|| is obtained that is proportional to the magnetic pressure in a cold plasma. Its integral along the magnetic field, F=−∫E_||ds, is proportional to ε^2m_iv^2_A. One-dimensional, fully kinetic, electromagnetic particle simulations verify the theoretical predictions for small-amplitude waves. Further, they demonstrate that eF becomes of the order of ε(m_iv^2_A+Γ_eT_e) in large-amplitude [ε~O(1)] oblique shock waves. These theory and simulations indicate that E_|| in magnetosonic waves can be strong in a strong magnetic field. | |||||
