MDCAT Physics MCQ #942

  1. Question 1

    Q1. A 20-year-old student is studying Faraday's law of electromagnetic induction. What is the induced EMF in a coil of 100 turns, 2 meters long, with a changing magnetic flux of 0.5 T*m^2/s?

    • A) 0.1 V
    • B) 0.5 V
    • C) 1 V
    • D) 10 V

    Answer: 1 V

    Explanation: The induced EMF is given by the product of the number of turns, length, and rate of change of magnetic flux. 0.1 V is too low, 0.5 V is half the expected value, and 10 V is too high.
