generate no current,since they cut practically no lines of magnetism, andthat if two coils were placed on the ring so as to bemoving past the line, A—B, they would be generating amaximum amount of current. By connecting these four THEORY OF DYNAMOS. 31 coils as shown in figure 12, we will generate… … FIGURE 12.—GRAMME RING ARMATURE.FOUR coil. TYPE. This multipljdng of coils can be carried on with econ-omy, until we have some dynamos of this type, havinghundreds of coils, and giving practically a perfectly con-tinuous current. The proper placing of the armature coils in the mag-nelic field…
