Answer 2

Answer:

magnetic compass needle is held closed above a horizontal wire carrying a current towards the south. How the N-pole will deflect?

Explanation:

The magnetic field is always from north to south. In our case, it travels from left to right(if you stand facing towards north). Hence the north pole of the magnetic needle deflects towards east(since the north and south pole attracts).
