A galvanometer coil `5 cm xx 2 cm` with 200 turns is suspended vertically in a field of `5 xx 10^-2 T`. The suspension fibre needs a torque of `0.125 x10^-7 N -m` to twist it through one radian. Calculate the strength of the current required to be maintained in the coil if we require a deflection of `6^@`.
