What reading level is The Effect of a Superposed Constant Field Upon the Alternating Current Permeabil book?
To quickly assess the difficulty of the text, read a short excerpt:
The equation of the curve is of the form W = k B m a .
From this curve a = 2 . 13. From a similar curve for Ring II, for H from . 025 to 3 . 5 gausses, a = 2 . 35. The alternating cur- 10 rent permeability for Ring II rises from an initial value of 100 to a value of 525 at H = 3 . 5 without indications of a maximum.
For Ring I, the exponent of B m in the above equation is near to the value 2. 16, which is the exponent of B m from ballistic measurements. For Ring II the exponent for the total lo...ss is 2 . 35 ; for the hysteresis loss alone it is 1 . 69 from the static curves. It was not expected that these two exponents should be the same for the reasons that they cover a different range of inductions; the alternating current loss includes eddy current losses; and the actual shapes of the hysteresis loops for very slow cycles is very different from those for very rapid cycles, as was shown by Ewing. 1 Alternating CurrcritPetmeability.
