A magnetic compass shows a deflection when placed near a current-carrying wire. How will the deflection of the compass get affected if the current in the wire is increased? Support your answer with a reason.

Answers (1)

Solution:
If the current is increased in the conductor the deflection of the compass needle increases. This happens because the strength of the magnetic field varies directly as the magnitude of the electric current or the current passing through the wire.
