When a current is switched on through a wire, the wire starts behaving as a magnet. Hence, when a compass needle is placed near the given current carrying wire, it gets influenced by the magnetic effect of electric current and gets deflected from its north- south position.

Answer 2

Answer:

When a magnet is brought close to it, the needle gets deflected. When an electric current passes through a wire, it behaves like a magnet. This magnetic effect of the electric current makes the compass needle deflect from the north-south direction.
