away, making it atthe same time revolve in order to change the direction ofthe magnetizing force, which grows feebler as the distancefrom the magnet increases. Figure 19 is intended to show the difference existing be-tween the neutral state and that of zero magnetization. Abar in the neutral state… … Fig. 19. return of the magnetizing force to zero has produced theloop BC\ then the values of the field have recommenced todecrease. A new retrogression has occurred at D, chosenso that the curve of magnetization passes through the 66 MAGNETISM. origin. At the moment of passing through the origin,…
