Question

why a magnetic neddle deflects in the presance of a current carrying conductor? ​

Answer 1

Answer:

The compass needle is a small magnet. That's why when a compass needle is brought near a bar magnet, its magnetic field lines interact with that of the bar magnet. Hence, a compass needle gets deflected near the magnet bar.
