While applying Fleming's right hand rule the central (middle) finger of right hand indicates

Options

A. the direction of magnetic field
B. the direction of rotation of conductor
C. the direction of current being flown
D. the direction of induced current

Explanation

To solve the question regarding Fleming's right-hand rule and what the central (middle) finger indicates, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Fleming's Right-Hand Rule**:
- Fleming's right-hand rule is a mnemonic used to determine the direction of induced current when a conductor moves through a magnetic field.

2. **Identify the Fingers**:
- In Fleming's right-hand rule, the right hand is used, and the three fingers (thumb, index finger, and middle finger) are arranged in such a way that they are mutually perpendicular to each other.

3. **Assign Meanings to Each Finger**:
- **Thumb**: Represents the direction of motion of the conductor (or the direction of force).
- **Index Finger**: Represents the direction of the magnetic field (from North to South).
- **Middle Finger**: Represents the direction of the induced current.

4. **Conclusion**:
- According to the rule, the middle finger indicates the direction of the induced current when a conductor moves through a magnetic field.

5. **Answer the Question**:
- Therefore, the correct answer to the question "While applying Fleming's right hand rule the central (middle) finger of right hand indicates" is the direction of the induced current.

### Final Answer:
The middle finger indicates the direction of the induced current.
