Electromagnetic Induction

In Fleming's right-hand rule, the thumb, the forefinger and the middle finger if held mutually at right angles represent respectively, the

  1. A.motion, the field and the induced current
  2. B.induced current, the motion and the field
  3. C.field, the induced current and the motion
  4. D.induced current, the field and the motion.
Show the answer and explanation

Answer: A (motion, the field and the induced current)

Explanation

In the right-hand (dynamo) rule: thuMb = Motion, First finger = Field, seCond finger = induced Current.
