Assertion : A compass needle is placed near a current carrying wire. The deflection of the compass needle decreases when the magnitude of the current in the wire is increased.
Reason : The strength of a magnetic field at a point near the conductor increases on increasing the current.
Answer:
(d) Assertion is False but the reason is True
The magnetic field of a conductor is directly proportional to the amount of current flowing through it. The deflection of the compass needle placed near a current carrying wire increases as the magnitude of current increases because the strength of magnetic field also increases.
