MCQ
A moving coil type of galvanometer is based upon the principle that:
  • ✓
    Coil carrying current experiences a torque in magnetic field.
  • B
    A coil carrying current produces a magnetic field.
  • C
    A coil carrying current experiences impulse in a magnetic field.
  • D
    A coil carrying current experiences a force in a magnetic field.
✓

Answer

Correct option: A.
Coil carrying current experiences a torque in magnetic field.

In a moving coil type of galvanometer needle deflects when torque in magnetic field is non $-$ zero.
So, a moving coil galvanometer is based upon the principle that coil carrying current experiences a torque in a magnetic field.
