Temperature coefficient of magnetic permeability within the working range (1915)
National Bureau of Standards · leaf 12
0° Sanford] Temperature Coefficient of Permeability changes sign in some cases and not in others. The wrought ironboth as received and annealed shows this change, while the steelshows it only in the annealed condition. Cast iron shows quitedifferent characteristics, according to the heat treatment… … FiG. 5.—Showing percentage change in induction for a given magnetizing force due to 1 degree rise 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, low-carbon steel…
