  We demonstrated that the chiral soliton lattice formed out of a chiral
helimagnet exhibits coherent sliding motion by applying a time-dependent
magnetic field parallel to the helical axis, in addition to a static field
perpendicular to the helical axis. To describe the coherent sliding, we use the
collective coordinate method and numerical analysis. We also show that the
time-dependent sliding velocity causes a time-varying Berry cap which causes
the spin-motive-force. A salient feature of the chiral soliton lattice is
appearance of the strongly amplified spin motive force which is directly
proportional to the macroscopic number of solitons (magnetic kinks).
