various sets of coils is similarto that of the Brush machine; that is, the set of coils in theposition of least action is disconnected entirely from the 1952 APPLIED ELECTRICITY. circuit; those near the position of maximum action are con-nected in parallel, and in series (by external connection… … Fig. 1157. is directly under a pole-piece, as at N; for when in this posi-tion all the lines of force from the pole-piece N pass directlythrough the center of the coil, which, therefore, cuts none ofthe lines of force. As soon as the coil moves from this posi-tion, one side begins to cut the lines…
