Electric Motor Open Model and density determinationElectric Motor Open Model It can demonstrate the structure and principle of DC generator and AC generator. Th specific principle is the closed principal iron ring. The inner side is equipped with a pair of electromagnets. The coils of the two electromagnets are connected in series, and the binding posts are mounted on iron ring. Via operation, you kids know how motor works, cultivate children's curiosity about science, and regard science as a child's
