  1. Question 1

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

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

    Answer: 104.7 V

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