{b) Magnetization imder constant tensions: (/, H)r. 



The magnetization increases steeply in low fields and after 

 2)assing through an inflexion point, gradually approaches satura- 

 tion. The eilect of tension is considerably large and always to 

 diminish magnetization ; curves (7, 11), ■ become less steep in weak 

 fields with the increasing tension, and tend to ap})roach each other 

 in strong fields. If we compare 0/ obtained from (/, H),- with 

 tliat from (o/, 'i),, fur the same values of // and T, the former 

 is found to be a little numerically greater than the latter. The 

 dotted line in Fig. 17 represents the A'alues of of as deduced 

 from (/,//)/.
