    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.
