A new spinmotive force is predicted in ferromagnets with the spin-orbit coupling. Theory of spinmotive force is extended, in which a time-varying electric field is found to be able to induce a spinmotive force with the static and uniform magnetization. The spinmotive force can be electrically investigated free from the inductive voltage owing to the absence of dynamical magnetization, and can be tuned by the external electric fields. We theoretically demonstrate the spinmotive force in two systems; electric voltage measurement in a single ferromagnet and spin injection from a ferromagnet into an attached nonmagnet.
