  1. Question 1

    Q1. A changing magnetic field induces an electromotive force in a coil. What is the direction of the induced current?

    • A) Opposite to the direction of the changing magnetic field
    • B) Along the direction of the changing magnetic field
    • C) Perpendicular to the direction of the changing magnetic field
    • D) Dependent on the orientation of the coil

    Answer: Opposite to the direction of the changing magnetic field

    Explanation: The induced current is opposite to the direction of the changing magnetic field, according to Lenz's law.
