Question

Fleming’s Right-hand rule gives

• A. Magnitude of the induced current
• B. Magnitude of the magnetic field
• C. Direction of the induced current
• D. Both, direction and magnitude of the induced current

Answer 1

The correct option is C

Direction of the induced current

Explanation for the correct option:

Option C: Direction of the induced current

Fleming's right-hand rule:

1. When a conductor moves in a magnetic field, the current is induced.
2. Fleming's right hand rule helps us to find the direction of the induced current.
3. The right hand is held with the thumb, index finger, and middle finger mutually perpendicular to each other.
4. The thumb is pointed in the direction of motion of the conductor, the index finger gives us the direction of the field and the middle finger gives the direction of the induced current.
5. Hence, Fleming's right-hand rule helps us in finding only the direction of the induced current.

Explanation for the incorrect options:

Option A, B and D.

1. Fleming's right-hand rule helps us in finding only the direction of the induced current.
2. It is not possible to find the magnitude using this method.
3. Hence, these options are incorrect.

Therefore, Option C is the correct option.
