  1. Question 1

    Q1. In a transformer, the magnetic field is generated by the primary coil. What is the effect of increasing the number of turns in the primary coil on the magnetic field?

    • A) The magnetic field increases linearly with the number of turns in the primary coil.
    • B) The magnetic field remains constant with the number of turns in the primary coil.
    • C) The magnetic field decreases exponentially with the number of turns in the primary coil.
    • D) The magnetic field is independent of the number of turns in the primary coil.

    Answer: The magnetic field increases linearly with the number of turns in the primary coil.

    Explanation: Increasing the number of turns in the primary coil increases the magnetic field due to electromagnetic induction, as the number of magnetic field lines increases proportionally.
