    Answer:

    The maximum  emf generated in the coil is 60527.49 V

    Explanation:

    Given;

    area of coil, A = 0.320 m²

    angular frequency, f = 100 rev/s

    magnetic field, B = 0.43 T

    number of turns, N = 700 turns

    The maximum emf generated in the coil is calculated as,

    E = NBAω

    where;

    ω is the angular speed = 2πf

    E = NBA(2πf)

    Substitute in the given values and solve for E

    E = 700 x 0.43 x 0.32 x 2π x 100

    E = 60527.49 V

    Therefore, the maximum  emf generated in the coil is 60527.49 V
