Brown — Mechanical Stress and Magnetisation of Iron.

Stress in Grammes per sq. cm. 

 Fig. 4. 



This curve indicates that, as the load increases, the circular magnetisation 

 in the wire decreases at a rapid and uniform rate up to a stress of 27 x 10' 

 grammes per sq. cm., which is about the -^-^ part of 65 x 10^ grammes per sq.
