H. NAGAOKA AND K. HONDA : 



one^^ of us investigated the transient current for iron and 

 nickel wires. It was then found that the current due to twist- 

 ing was opposite in direction in tliese two metals and that it 

 reached a maximum in moderate fields. As the magnetizing 

 current was not very strong, no conclusive measurements were 

 made as regards the nature of the transient current in strong 

 fields. In order to make this point clear and see if any inti- 

 mate relation with the Wiedemann effect could be traced, fresh ex- 

 periments were undertaken by the. same method as before. We 

 have to notice that the ferromagnetic wire was so placed in the 

 axial line of the magnetizing coil that it lay in nearly uniform field. 

 Some of the measurements of the transient current for iron 

 and nickel wires are given in the following table and in Fig. 4.
