In the Fleming‘s left hand rule index finger indicates the direction of the:

Correct option is A

The correct answer is (a) magnetic field

• Fleming’s Left-Hand Rule is used to determine the direction of the force experienced by a current-carrying conductor in a magnetic field.

• According to this rule:

  • The index finger represents the direction of the magnetic field (from North to South).

  • The middle finger indicates the direction of the electric current.

  • The thumb represents the direction of the magnetic force or the motion of the conductor.

Information Booster:

• Fleming's Left-Hand Rule is applied in the working of electric motors, where the force (motion) is generated due to the interaction of the electric current and the magnetic field.

• Right-hand rule is used to determine the direction of induced current in generators (electromagnetic induction).

Additional Information:

• This rule helps explain how a motor works by converting electrical energy into mechanical energy. The opposite, in the case of generators, uses the right-hand rule to determine the direction of induced current when mechanical motion is applied.
