A current carrying wire is experiencing a magnetic force in a magnetic field. What happens to the direction of the magnetic force on the wire, if the current in the wire is reversed?
a. The magnitude of the force remains unchanged, but it reverses direction.
b. The magnitude of the forces decreases, but it remains in the same direction.
c. The magnitude of the force remains unchanged, but it is oriented perpendicular to the direction of the original force.
d. Nothing. The magnitude and direction of the force remain unchanged.
