easing thestrength of the field, we measure the intensity of magnetisationfor every value of F, which, in this case, is the same as H. Theresults may be represented by a curve, the values of F formingthe abscissae, and those of A the ordinates. And since B = F +47rJ., or = iirA nearly for highly… … Fig. 178. Ill the case of iron or its varieties, or cobalt, or nickel, thecurve has always the same general appearance. Three parts may be distinguished: thefirst (Fig. 178), cor-responding to verysmall magnetisingjields, in which theintensity increasesvery slowly, but atfirst proportionallyto the…
