  1. Question 1

    Q1. A coil has 500 turns and is rotated in a magnetic field. If the flux linked with the coil changes from 0 to 1 Wb in 1 s, induced emf is

    • A) 250 V
    • B) 500 V
    • C) 750 V
    • D) 1000 V

    Answer: 500 V

    Explanation: Induced emf = N(dφ/dt) = 500 * (1 / 1) = 500 V.
