Solution

The correct option is A
Deflect as a magnetic field is produced around the current-carrying conductor

When a compass needle is placed below a wire and a current is made to flow through the wire the needle deflects as a magnetic field is produced around the current-carrying conductor.

Oersted was the first to put forth the direct relation between _______ and magnetism. He conducted several experiments to determine the _______ of a current _______ wire. The following describes the Oersted experiment conducted to establish that a current carrying wire acts as a _______.
A long straight wire is connected to an external battery and an electric current is passed through it. When a magnetic needle is placed below the wire such that the wire is parallel to the axis of the magnetic needle and the current flows in the south to north direction, a deflection in the needle is observed. It is observed that the north pole of the needle is deflected westwards and as the _______ is increased, the deflection, _______ till the north pole of the needle turns towards exact west.
