gardingits condition. A better method of procedureis to obtain the throw for a reversalof the field, which of course gives2B instead of B, for any value ofH. Thus in Fig. 272, if the value ofthe magnetising field is Oil, and thisbe reversed to 0/t = - OA, B changes from 06 to 06, that is, the… … Fig. 272. X. CYCLE BY BALLISTIC METHOD 275 standardising throw 6i, and since the throw for a reversal is made in bothcases, the numerator and denominator in the quantity —, J! ^ ,, ^ are both halved, which of course leaves it unaltered, and the fact of reversalmay be ignored. The method of…
