▎ 摘 要
The drag current density under the solitary electromagnetic wave propagating in the graphene superlattice is calculated. The constant magnetic field influence on the charge dragged by such nonlinear wave is investigated. The dragged charge is shown to enhance by an order when the value of the magnetic field intensity reaches the order 10 T. The value of the magnetic field intensity which leads to a change in the sign of the dragged charge is calculated. The dependence of this value on the solitary wave velocity is studied.
