Magnetohydrodynamics mode can be triggered by external resonant magnetic perturbations. Whether it is ideal mode or resistive mode, it breaks the toroidal symmetry in tokamaks. When the toroidal symmetry is broken, the neoclassical transport is enhanced because collisionless particles are not confined. In this study, we calculate the neoclassical particle transport when kink-like modes are present near the plasma edge or boundary.
