Question

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.\

Professor PC Thomas Classes · Answer

(d) : As we increase the current in the wire, the magnetic field will increases near the conductor or current carrying wire. Therefore, the deflection of compass needle increase.
