  1. Question 1

    Q1. A coil is placed in a magnetic field such that its plane is perpendicular to the field. The coil is rotated by 90°. Change in flux is

    • A) 0
    • B) BA
    • C) -BA
    • D) 2BA

    Answer: BA

    Explanation: Initial flux = BA, final flux = 0, hence change in flux = BA.
