that for the latter. Moreover the maximum for the loaded wire 

 takes place in stronger field than for the unloaded. 



Corresponding- to the above, another set of experiments was 

 performed by the method of reversal, the strength of the field being 

 kept erpial to 19.7 throughout the course of experiment and the twists 

 being varied. The following are the readings; the curves being 

 shown in Fig. X V. 



The examination of these curves shows the increase of the tran- 

 sient current when the diameter of the wire becomes greater. As 1 

 have already noticed before, the transient current always reaches its 

 maximum value for a certain angle of twist. The angle giving max- 

 imum current varies with the thickness of the wire. The thicker the 

 wire, the smaller the amount of twist which is to lie applied to make 

 the current arrive at a maximum, as will be seen from the following:
