    e = 30 V

    Explanation:

    given,

    N = 30 turns

    Area = 0.25 m²

    angular speed = ω = 100 rad/s

    Magnetic field = 0.04 T

    maximum induced emf in the loop = ?

    e = N B A ω

    e = 30 x 0.04 x 0.25 x 100

    e = 30 V

    hence, the maximum emf induced in the loop is equal to e = 30 V
