Question

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

Answer 1

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 2

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.
