$\large\mathbb \red{ QUESTION }$

When the current is switched on through wire, a compass needle kept nearby gets deflected from its north-south position. Explain.

$\mathbb \purple{ ANSWER }$

• 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.
