  1. Question 1

    Q1. A superconducting coil is placed in a magnetic field. What is the reason behind the coil's ability to maintain its magnetic field without any energy loss?

    • A) The coil is able to maintain its magnetic field due to the absence of electrical resistance.
    • B) The coil is able to maintain its magnetic field due to the presence of a permanent magnet.
    • C) The coil is able to maintain its magnetic field due to the absence of electromagnetic induction.
    • D) The coil is able to maintain its magnetic field due to the thermal expansion of the coil.

    Answer: The coil is able to maintain its magnetic field due to the absence of electrical resistance.

    Explanation: The coil is able to maintain its magnetic field without any energy loss due to the absence of electrical resistance, as it is a superconductor.
