all points between the centerand end of a test specimen 40 cm long between yokes. The yokeconsisted of a three-piece return circuit such as is shown in Fig. 10.Here the yoke effect is very marked, due to the great differencein cross section of specimen and yoke. It is to be observed thatthe… … i±j w Fig. 4.—Showing the Magnitude and Distribution of Flux along the Length of a Rod 47 cm Longunder Varying Conditions. Main Magnetizing Current Constant.
