place very slowly beyond a certain angle of twist. 



15. — Everything being the same as in (14), the transient current 

 produced by reversing the direction of the magnetizing force in- 

 creases at first with the increase of twist, but it soon reaches a 

 maximum. After this a slow decrease of the current takes place, 

 and when the twist is very large, the current becomes very small. 



16. — Loading the wire and proceeding in the same way as in (15), the 

 current decreases rapidly after passing the maximum, and soon 

 after becomes very small. 



17. — When the thickness of the wire is different, the transient current 

 is in general greater as the wire becomes thicker. The current in 

 weak fields is smaller with the thick than with the thin. The 

 maximum current occurs in higher magnetizing field as the thick- 

 ness is increased. 



18. — With the magnetizing force constant, and the amount of 

 twist variable, the maximum current occurs for smaller twists as 

 the wire becomes thicker.
