Recently it has been recognized that the electromotive force (emf) can be induced just by the spin
precession where the generation of the electromotive force has been considered as a real-space topological
pumping effect. It has been shown that the amount of the electromotive force is independent of the
functionality of the localized moments. It was also demonstrated that the rigid domain wall (DW) motion
cannot generate electromotive force in the system. Based on real-space topological pumping approach in
the current study we show that the electromotive force can be induced by rigid motion of a deformed
DW. We also demonstrate that the generated electromotive force strongly depends on the DW bulging.
Meanwhile results show that the DW bulging leads to generation of the electromotive force both along the
axis of the DW motion and normal to the direction of motion.
