om 900° given induction were determined. The values calculated fromthese three curves indicate that, within the limits of experimentalerror, the temperature coefficient in this range is independent oftemperature. Figs. 1,2, and 3 give the normal induction curves at 25° andthe temperature… … Vo per dejree Fig. 4.—Showing percentage change in magnet-izing force for a given induction due to 1 degreerise in temperature C-i, cast iron as received C-2, cast iron quenched from 10000 C-3, cast iron annealed from 900 ° W-i, wrought iron as received W-2, wrought iron annealed from 900° S-i,…
