Assertion (A): The deflection of a compass needle placed near a current carrying wire decreases when the magnitude of an electric current in the wire is increased. 1 Reason (R): Strength of the magnetic field at a point due to a current carrying conductor increases on increasing the current in the conductor.
Explanation
The assertion is correct because the deflection of a compass needle placed near a current-carrying wire decreases when the magnitude of an electric current in the wire is increased. The reason is also correct because the strength of the magnetic field at a point due to a current-carrying conductor increases on increasing the current in the conductor.
