Two types of magnetizing yokes were used in the present
study. The Type I magnetizing yoke had an exciting coil of 820
turns, distance between the poles was 165 mm and a pole cross-
section of 25 mm  25 mm. The second yoke was a Type II
magnetizing yoke, which had an exciting coil of 600 turns,
distance between the poles was 130 mm and a pole cross-section
of 20 mm  20 mm. The magnetizing yoke was placed at the
center of the test object, indicated as the 0 mm position in an
(x,y)-coordinate system; it was also placed at positions of 40, 80
and 120 mm from the type A standard test shim in the transverse
direction (y direction).
