12th Class Physics Magnetism Question Bank Assertion And Reason (MCQs) - Magnetism and Matter

  • question_answer
    ASSERTION: Basic difference between an electric line and magnetic line of force is that former is discontinuous and the latter is continuous or endless.
    REASON: No electric lines of forces exist inside a charged body but magnetic lines do exist inside a magnet.

    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: A

    Solution :

    In case of the electric field of an electric dipole, the electric lines of force originate from positive charge and end at negative charge. Since isolated magnetic lines are closed continuous loops extending throughout the body of the magnet.
