A single, continuous loop of conducting wire is mounted on a glider, which travels on a frictionless air track with an initial velocity v. When the front edge of the loop enters the magnetic field B pointing out of the page as shown:

• there is a clockwise current in the loop, and the glider slows down.

• there is a counterclockwise current in the loop, and the glider slows down.

• there is a clockwise current in the loop, and the glider speeds up.

• there is a counterclockwise current in the loop, and the glider speeds up.
