Which of the following statements is true about a current carrying wire in a magnetic field

The answer is: reversing the current direction will cause the force deflecting the wire to perpendicular to the magnetic field but in the opposite direciton.

Hope this  helps!

Answer;

Reversing the current direction will cause the force deflecting the wore to be perpendicular to the magnetic field but in the opposite direction.

Explanation;When a current carrying conductor or wire is put in a magnetic field it experiences a force that acts on it in accordance to the Fleming right hand rule.According to Fleming right hand rule when the right hand is held such that the first two fingers and thumb are held perpendicularly; the first finger points the direction of the magnetic field while the second finger points the direction of current, then the thumb will experience.Therefore, changing the direction of current will result to the force deflecting the wire to be perpendicular to the magnetic field but in the opposite direction.
