turns. Those inductors included between lines ad and hecarry current in the opposite direction to that circulating aroundthe field poles, and consequently produce an m. m. f. opposed to thatof the main field. The turns enclosed by the lines ad and he areknown as the back ampere-turns. The breadth… … Fig. 67. Clover-Leaf Design ofField Cores carry 25 amperes, since there are two paths in parallel; and as thenumber of cross-magnetizing turns is 8, and the number of demag-netizing turns is 4, the cross-ampere-turns would be 25 X 8 = 200;t nd the number of back ampere-tnrns would be 25 X 4 = 100.…
