Question

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

Answer 1

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.

Answer 2

Answer:

It is because when the current is switched on through the wire a compass needle kept nearby gets deflected from north south position due to the magnetic field produced by the current carrying conductor. The compass needle is also a small piece of magnet and when it is kept near a current carrying wire which is a electromagnet it deflects from north south.
