Assertion (A): In Fleming’s Left Hand Rule, the direction of magnetic field, force and current are mutually perpendicular.

Reason (R): Fleming’s Left hand Rule is applied to measure the induced current.




Fleming's left hand rule is used to find the direction of the force/ motion of a conductor.

Fleming's right-hand rule states that if we hold the forefinger, the middle finger and the thumb of our right hand at right angles to one another such that

  • Forefinger points in the direction of magnetic field
  • Thumb in the direction of the motion of conductor
  • Then the direction which the middle finger points gives the direction of the induced current.


  • Assertion is true.
  • Reason is false.

So, the correct answer is (c)
