    Answer:

    54.17volts

    Explanation:

    Induced emf in a coil placed in a magnetic field can be expressed as E = N¶/t where

    N is the number of turns = 150turns

    ¶ is the magnetic flux = magnetic field strength (B) × area(A)

    ¶ = BA

    B = 0.65T

    A = 1.0m²

    t is the time =1.8s

    Substituting this value in the formula

    E = NBA/t

    E = 150×0.65×1.0/1.8

    E = 54.17Volts

    The induced emf in the coil is 54.17Volts
