EFl'JXT OF STJ:BS.'S ON MA( iMKTIZATlOX. 13 



Tlic change of inagiietiziition by tension nndei- dilTerent in- 

 itial loadings, wlieie the demagnetization was always elfected with 

 the initial load, is given in tlie following table. For an e(iual 

 increment ^»7' of 7', o/, decreases i'a})idly, as the initial 7' increases, 

 whereas in the graduated a[)[)lications of tension, o/.. increases 

 nearly })ro])ortional to uT. The difVerence between these two 

 values of nl, is considerable.
