For a body in circular motion, the angular momentum is conserved. The interactions cannot either change the direction or the magnitude of the system's total momentum. As long as there isn't any torque acting on the body, angular momentum remains constant in magnitude and direction.
The direction of angular momentum is parallel with the angular velocity vector.
