Burrows Permeameter
This instrument, used for determining the normal magnetic induction curve and the hysteresis loop for a straight round specimen, was designed by Charles W. Burrows of the National Bureau of Standards around 1909, utilizing the idea of a distributed and adjustable magnetomotive force. Its magnetic circuit consists of two approximately identical bars 250 millimeters long, their ends being clamped by brass screws in two connecting yokes of high permeability. Yoke ends are hemispherical to minimize flux leakage into air. The main magnetizing solenoids consist of 10 layers of No. 18 copper wire wound with 7.958 turns per centimeter. They extend over the entire length of the two bars between the yokes. A compensating coil with four windings in series is added at the four ends. The main test coil is wound closely over the middle quarter of the bar chosen as a test specimen. On each side of this, midway between it and the yokes, the two halves of a second search coil are wound. A third16 x 35 x 20 c
