Experimentally, it is observed that the low driveSy, is several times the high-drive value. In this section, following themethod of Williams, Shockley, and Kittel,^ flux reversal by the move-ment of a single wall will be treated. Only the circular flux case will beconsidered. The technique used to obtain Sw is identical to that used in except it is postulated that a single wall concentric to the wiremoves either from the wire surface inward, or from the wire axis result is independent of the direction in which the wall moves. As-sume the wall moves from r = 0 to r = ro , as indicated in Fig. 8. In-.
