### Step-by-Step Solution: 1. **Understanding the Moving Coil Galvanometer (MCG)**: The moving coil galvanometer is an instrument used to measure small electric currents. It operates based on the interaction between a current-carrying coil and a magnetic field. 2. **Principle of Operation**: The underlying principle of the MCG is that when a current-carrying coil is placed in a magnetic field, it experiences a torque. This torque is due to the magnetic forces acting on the current-carrying conductors within the coil. ...
