alleryA moving coil galvanometer uses a radial magnetic field so that:
Athe coil rotates faster
Btorque is zero
Conly the centre of the coil experiences B
Dtorque is independent of coil position
Answer & Solution
Correct answer: D. torque is independent of coil position
Radial field keeps sin θ = 1 always, giving torque ∝ I (linear scale).
