As the motion of positive charge is the direction of current in the wire. From the right-hand curl rule, the magnetic field direction will be outside the paper or the screen. As the <span>wire runs left to right and carries a current in the direction from left to right, the magnetic field lines will be outside the screen.</span>
An airplane is flying at a constant speed in a positive direction. It slows down when it approaches the airport where it's going to land. this is an example of negative acceleration (D).
