Thepath of the magnetic flux is indicated by the dotted line1^.2-3-J/., and when the inductor revolves, the lines of forcesweep across the stationary coils and thus set up the requiredE. M. F. This machine has the advantage of having nomoving wire about it, but machines of the revolving-fieldtype, such as shown in Fig. 52, have the advantage of using. ^Q
