If the needle deflects East, what would happen if you reversed the current?

the north and south poles will exchange places.

Explanation:

The intensity of the magnetic field produced around the conductor depends on the volume of current. Unless the position of the current is inverted, the compass needle travels in the same position, since the polarity of the magnetic field is inverted.

hope I helped!
