Solution:

When the current in a conductor in a magnetic field is reversed, the force direction is reversed as well.
Explanation :

Extend the thumb, forefinger, and middle finger of the left hand according to Fleming’s left Hand Rule. These are all perpendicular to one other. The thumb points in the direction of the force produced on the conductor. The forefinger points in the direction of the magnetic field and the middle finger points in the direction of the current. As a result, if the current in a conductor placed in a magnetic field is reversed, the force direction is reversed as well.
