Fleming’s right-hand rule can be used to determine the direction of induced current when the angle between the magnetic field and the motion of the conduction is:

Correct option is A

The correct answer is (A)

Fleming's Right-Hand Rule:

Fleming's right-hand rule is a rule used to determine the direction of induced current in a conductor when it moves in a magnetic field. It is primarily used in generators or situations involving electromagnetic induction.

How it works:

1.      Thumb: Points in the direction of the motion of the conductor (relative to the magnetic field).

2.      First finger (Index finger): Points in the direction of the magnetic field (from North to South).

3.      Middle finger: Points in the direction of the induced current (conventional flow from positive to negative).   

Purpose:

Fleming's right-hand rule helps in understanding how mechanical energy is converted into electrical energy in devices like:

• Electric generators.
• Alternators.

Example:

• When a wire is moved perpendicular to a magnetic field, the right-hand rule predicts the direction of the induced current in the wire.
• This is the opposite of Fleming's Left-Hand Rule, which is used for motors (conversion of electrical energy into mechanical energy).
