wing may be measured with asmall coil and galvanometer. By passing the same currentsthrough both coils in Figs. 26 and 27 and comparing thenumber of magnetic lines produced, the permeability ofthe iron is found. If there are 100 turns in each coil, and one ampere isflowing through each coil,… … Figure 27Same coil as in Figure 26 with iron core. In the above table the first column represents the num-ber of lines of force which flow through the iron. The sec-ond column is the permeability or multiplying power of theiron. The third column is the number of magnetic lines 60 there would be in…
