      Question

      In a coil with n turns, what happens to the induced

      electromotive force (EMF) if the number of turns is doubled while the magnetic flux remains constant?
      A It remains unchanged Correct Answer Incorrect Answer
      B It doubles Correct Answer Incorrect Answer
      C It halves Correct Answer Incorrect Answer
      D It quadruples Correct Answer Incorrect Answer

      Solution

      According to Faraday's Law of electromagnetic induction, the induced EMF in a coil is proportional to the number of turns (n). Thus, doubling the number of turns while keeping the magnetic flux constant will double the induced EMF.
