The controlling couple is proportional to the deflection $, and tothe couple c for unit twist(one radian) of the suspen-sion, the upper end… … Hence for a well-designedinstrument the current isproportional to the deflectionitself, since the field is cer-tainly of constant value until6 attains much larger valuethan that occurring in anypiobable experiment. To in-crease the sensitiveness, c maybe diminished, and A, n, andH increased, c…
