In moving coil galvanometer, the coil is wound over the………………..frame in order to make the galvanometer……………. .

Answer

To solve the question, we need to identify the specific frame over which the coil of a moving coil galvanometer is wound, and understand the purpose of this design choice.

### Step-by-Step Solution:

1. **Understanding the Moving Coil Galvanometer**:
- A moving coil galvanometer (MCG) is an instrument used to detect the presence of electric current in a circuit. It operates based on the interaction between a magnetic field and a current-carrying coil.

2. **Construction of the Galvanometer**:
- The galvanometer consists of a coil that is placed between the poles of a magnet. The coil is free to rotate and is suspended in such a way that it can respond to the magnetic field created by the current flowing through it.

3. **Identifying the Frame**:
- The coil in a moving coil galvanometer is wound over a **metallic frame**. This frame is crucial for the operation of the galvanometer.

4. **Purpose of the Metallic Frame**:
- The metallic frame serves multiple purposes:
- It provides structural support to the coil.
- It helps in creating a uniform magnetic field around the coil.
- It allows the galvanometer to act like a dead beat, meaning it can quickly settle to a steady reading without oscillating.

5. **Final Answer**:
- Therefore, the complete statement is: "In moving coil galvanometer, the coil is wound over the **metallic** frame in order to make the galvanometer **dead beat**."
