K. nONDA : ON THE MUTUAL INFLUENCE 



C.G.S. units. The results are given in the following table and 

 in Fis-. 4. 



TABLE III. 



It is to be noticed that the intensity of magnetization in 

 the longitudinal direction is, in this case, always less thnn that 

 in the former case for the same longitudinal and transverse 

 fields, as will be seen from Figs. 3 and 4. 



Next keeping the longitudinal field constant, the axial cur- 

 rent was changed cyclically between +12.5 and —12.7 ampères, 

 and the hysteresis curve as shown in Fig. ö was obtained. The 

 magnetizing field was 11.0 C.G.S. units and the corresponding 

 intensity of magnetization was 770 C.G.S. units. It increased 

 to 845 C.G.S. units, when the cyclic state arrived. 



The hysteresis curve attending the cyclic changes of longi- 

 tudinal field, while the circular field is kept constant, is the 

 same as the ordinary hysteresis curve, except that the area is 

 considerablv reduced, in accordance with what is well known.
