A horizontal 6m-long wire running from west to east is in a 0.03T magnetic field that is directed toward the southwest.

a) If a 4.5A current flows east through the conductor, what is the magnitude and direction of the force on the wire?

b) What is the magnitude and direction of the force if the current direction is reversed?
