Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:


Assertion : A compass needle is placed near a current carrying wire. The deflection of the compass needle decreases when the magnitude of an electric current in the wire is increased.


Reason : Strength of a magnetic field at a point near the conductor increases on increasing the current.

  • a)
    Assertion (A) is false but reason (R) is true.

  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

  • c)
    Assertion (A) is true but reason (R) is false.

  • d)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

  • e)
    Both Assertion and Reason are false.

Correct answer is option 'A'. Can you explain this answer?

Assertion: A compass needle is placed near a current-carrying wire. The deflection of the compass needle decreases when the magnitude of an electric current in the wire is increased.

Reason: The strength of a magnetic field at a point near the conductor increases on increasing the current.

Explanation:
The given assertion and reason are both true, and the reason correctly explains the assertion.

Assertion Explanation:
When a current-carrying wire is placed near a compass needle, the needle gets deflected due to the magnetic field produced by the current. The deflection of the compass needle is directly proportional to the strength of the magnetic field. Therefore, if the magnitude of the electric current in the wire is increased, the strength of the magnetic field also increases.

Reason Explanation:
According to Ampere's law, the magnetic field produced by a current-carrying wire is directly proportional to the magnitude of the current. So, when the current in the wire is increased, the strength of the magnetic field at a point near the conductor also increases.

Conclusion:
The deflection of the compass needle decreases when the magnitude of the electric current in the wire is increased because the strength of the magnetic field at a point near the conductor increases with an increase in current. Hence, both the assertion and reason are true, and the reason is the correct explanation of the assertion.

Therefore, the correct answer is option 'A' - Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
