    Q1. A coil of 100 turns is rotated at 50 Hz in a magnetic field of 0.1 T. What is the induced EMF if the coil has an area of 0.02 m^2?

    • A) 100 V
    • B) 200 V
    • C) 50 V
    • D) 20 V

    Answer: 200 V

    Explanation: Faraday's law, most tempting option fails due to incorrect calculation
