  1. Question 1

    Q1. A coil of 100 turns is rotated at 1000 rpm in a magnetic field of 0.01 T. The maximum emf induced is

    • A) 10.47 V
    • B) 1.047 V
    • C) 104.7 V
    • D) 0.1047 V

    Answer: 104.7 V

    Explanation: ε = NABωsin(ωt), ε_max = NABω = 100 * 0.01 * (2π * 1000 / 60) = 104.7 V, using ω = 2πf.
