Two parallel wires I and II that are near each other carry currents i and $3$i both in the same direction. Compare the forces that the two wires exert on each other.

Wire I exerts a stronger force on wire II than II exerts on I.

Wire II exerts a stronger force on wire I than I exerts on II$.$

The wires exert equal magnitude attractive forces on each other.

The wires exert equal magnitude repulsive forces on each other.

The wires exert no forces on each other.
