### Step-by-Step Solution 1. **Understanding the Moving Coil Galvanometer**: - A moving coil galvanometer is an instrument used to measure small electric currents. It consists of a coil of wire suspended in a magnetic field. 2. **Structure of the Galvanometer**: - The galvanometer typically has a cylindrical structure with a magnetic field created by two magnets (North and South poles). The coil is placed within this magnetic field. ...
