Determination of magnetic induction in straight bars (1909)
National Bureau of Standards · leaf 41
examination of the surface of this test specimen showed thatan identifying number had been stamped very lightly upon therod at the place where the minimum of flux appeared. Thus itwould seem that the stamping had produced a hardening of themetal at this point, and a consequent lowering of the… … Fig. 21.—Showing Irregularities in the Flux due to Irregularities in the Test Bar itself in aMagnetic Circuit consisting of Two Rods and Two Yokes excited by a Constant Magneto-motive Force. Curve I with yokes close to solenoids. Curve II with yokes 1.5 cm from ends of solenoids. Curve III with…
