A rectangular coil of area `5.0xx10^(-4) m^2` and 60 turns is pivoted about one of its vertical sides. The coil is in a radial horizontal field of 90 G (radial here means the field liners are in the plane of the coil for any rotation). What is the torsional constant of the hair spring connected to the coil if a current of 2.0 mA produces an angular deflection of `18^@`?

A rectangular coil of area 5.0 xx 10^(-4) m^(2) and 40 turns is pivoted about one of its vertical sides. The coil is in a horizontal field of 80 gauss. If a current of 0.20 mA produces an angular deflection of 20^(@) , then the torsional constant of the hair spring connected to the coil is (in Nm/degree)
