  1. Question 1

    Q1. An increasing magnetic field induces an electromotive force in a coil. What is the magnitude of the induced emf proportional to?

    • A) The rate of change of the magnetic field
    • B) The area of the coil
    • C) The number of turns of the coil
    • D) The resistance of the coil

    Answer: The rate of change of the magnetic field

    Explanation: The magnitude of the induced emf is proportional to the rate of change of the magnetic field, not the area, number of turns, or resistance of the coil.
