ON TRANSIENT ELECTRIC CURRENTS. 



375 



always increasing as the twist was increased. This is in harmony 

 with the view of aeolotropic magnetic susceptibility. In the experi- 

 ments now to be described, the same series of experiments were per- 

 formed by subjecting the twisted wire to reversals of the magnetizing 

 forces. The results thus obtained are somewhat striking, and seem 

 incapable of explanation in terms of aeolotropic magnetic susceptibility. 



The experiment was tried in exactly the same way as for iron. 

 Out of a number of experiments made in this way, I give the follow- 

 ing, as showing the typical relation between the amount of twist and 

 the transient current. 



The following are the readings made with the thick wire; and 

 the corresponding curves are shown in Fig. XIII. 



The following give the observations made with the thin wire.
