What happens to the plane when the rudder is turned?

When the rudder is turned, it alters the airflow around the tail of the plane, creating a difference in pressure on either side. This differential pressure causes the plane to yaw, or rotate horizontally, in the direction of the rudder's deflection. For example, turning the rudder to the right will cause the nose of the aircraft to move to the right. This maneuver is essential for coordinated turns and maintaining directional control during flight.
