  1. Question 1

    Q1. A solenoid is placed near a permanent magnet. What is the reason behind the magnetic field generated in the solenoid?

    • A) The magnetic field is due to the thermal expansion of the solenoid.
    • B) The magnetic field is generated by the flow of electrons in the solenoid.
    • C) The magnetic field is due to the presence of the permanent magnet near the solenoid.
    • D) The magnetic field is due to the changing current in the solenoid.

    Answer: The magnetic field is due to the presence of the permanent magnet near the solenoid.

    Explanation: The magnetic field in the solenoid is generated by the presence of the permanent magnet, which induces a magnetic field in the solenoid due to electromagnetic induction.
