- gets reversed in direction
- increases in strength
- decreases in strength
- remains unchanged in strength and direction.

Answer
gets reversed in direction
Reason — By reversing the direction of current in a wire, the magnetic field produced by it gets reversed in direction because the polarity of the faces of the wire gets reversed.
