12th Class Physics Magnetic Effects of Current / करंट का चुंबकीय प्रभाव Question Bank Assertion And Reason (MCQs) - Moving Charges and Magnetism

  • question_answer
    ASSERTION: A circular loop carrying current lies in XY plane with its center at origin having a magnetic flux in negative Z-axis.
    REASON: Magnetic flux direction is independent of the direction of current in condenser.

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.

    C) If assertion is true but reason is false.

    D) If both assertion and reason are false.

    E) If assertion is false but reason is true.

    Correct Answer: C

    Solution :

    The direction of magnetic field due to current carrying conductor can be found by applying right hand thumb rule. When electric current is passed through a circular Conductor, the magnetic field lines near the center of the conductor are almost straight lines. Magnetic flux direction is determined only by the direction of current.
