    1068.23 V

    Explanation:

    number of turn, N = 21

    Area, A = 0.12 m^2

    Resistance, R = 24 ohm

    Magnetic field, B = 0.5 Tesla

    Frequency, f = 135 Hz

    The maximum induced emf is given by

    e = N x B x A x ω

    e = N x B x A x 2 x π x f

    e = 21 x 0.5 x 0.12 x 2 x 3.14 x 135

    e = 1068.23 V

    Thus, the induced emf is 1068.23 V.
