  1. Question 1

    Q1. A coil of wire is placed in a magnetic field and is observed to experience an induced emf. What is the direction of the current flowing through the coil?

    • A) Clockwise
    • B) Counterclockwise
    • C) The direction of the current is not affected by the induced emf
    • D) The direction of the current is affected by the direction of the magnetic field

    Answer: Counterclockwise

    Explanation: The direction of the current flowing through the coil is determined by Lenz's law, which states that the current flows in a direction such that the magnetic field induced by the current opposes the change in the original magnetic field.
