A moving coil galvanometer works on the torque on a:
ACharged plate in an electric field
BCurrent coil in a magnetic field
CMagnet in a changing flux
DResistor heated by current
Answer & Solution
Correct answer: B. Current coil in a magnetic field
Its coil carries current in a magnetic field and the torque is balanced by a spring.
