 3racktts indicate annealing at 800° C in vacuum. Parentheses indicate hardening by quenching from cheny-red.

TABLE 366. — Corrections for Ring Specimens. 



In the case of ring specimens, the average magnetizing force is not the value at the mean radius, 

 ;he ratio of the two being given in the table. The flux density consequently is not uniform, and 

 :he measured hysteresis is less than it would be for a uniform distribution. This ratio is also given 

 :or the case of constant permeability, the values being applicable for magnetizations in the neigh- 

 borhood of the maximum permeability. For higher magnetizations the flux density is more uni- 

 form, for lower it is less, and the correction greater.
