JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Faraday's and Lenz's Law

  • question_answer
    A magnet is brought towards a coil (i) speedly (ii) slowly then the induced e.m.f./induced charge will be respectively [RPMT 1997; MP PMT 2003]

    A)             More in first case / More in first case

    B)             More in first case/Equal in both case

    C)             Less in first case/More in second case

    D)             Less in first case/Equal in both case

    Correct Answer: B

    Solution :

               The magnitude of induced e.m.f. is directly proportional to the rate of change of magnetic flux. Induced charge doesn?t depend upon time.
