  1. Moving coil galvanometer is named from its construction principle.                                a. What is the principle of moving coil galvanometer?                                                   b. What is meant by high current sensitivity of moving coil galvanometer?

A moving coil galvanometer is based on the principle that a current-carrying coil or loop placed in a region of a magnetic field experiences a torque.

Current sensitivity of a galvanometer defines the deflection produced in the coil per unit current supplied to the galvanometer. A high current sensitivity implies a larger deflection for each unit rise in current.
