Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding the Moving Coil Galvanometer (MCG)**: - A moving coil galvanometer is an instrument used to detect and measure small electric currents. It operates on the principle of electromagnetic induction. 2. **Role of the Soft Iron Core**: - The soft iron core is placed within the coil of the galvanometer. Its primary function is to enhance the magnetic field produced by the coil when current passes through it. ...
