    Answer:

    Number of turns of wire(N) = 3,036 turns (Approx)

    Explanation:

    Given:

    Diameter = 13 Cm

    emf = 5.6 v

    Note:

    The given question is incomplete, unknown information is as follow.

    Magnetic field increases = 0.25 T in 1.8 (Second)

    Find:

    Number of turns of wire(N)

    Computation:

    radius (r) = 13 / 2 = 6.5 cm = 0.065 m

    Area = πr²

    Area = (22/7)(0.065)(0.065)

    Area = 0.013278 m²

    So,

    emf = (N)(A)(dB / dt)

    5.6 = (N)(0.013278)(0.25 / 1.8)

    5.6 = (N)(0.013278)(0.1389)

    N = 3,036.35899

    Number of turns of wire(N) = 3,036 turns (Approx)
