Which finger is used to denote the direction of motion of conductor in Fleming's right hand rule?

Options

A. Thumb
B. Forefinger
C. Little finger
D. Central finger

Explanation

To determine which finger is used to denote the direction of motion of a conductor in Fleming's right hand rule, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Fleming's Right Hand Rule**: This rule is used to find the direction of induced current when a conductor moves in a magnetic field.

2. **Identify the Fingers Used**: According to Fleming's right hand rule:
- The **Thumb** represents the direction of motion of the conductor.
- The **Index Finger** represents the direction of the magnetic field.
- The **Middle Finger** represents the direction of the induced current.

3. **Conclude the Answer**: Since the question specifically asks for the finger that denotes the direction of motion of the conductor, the answer is the **Thumb**.

### Final Answer:
The thumb is used to denote the direction of motion of the conductor in Fleming's right hand rule.
