title: "A long, straight horizontal wire carries a steady current \\(I\\) directed to the right. A rectangular conducting loop is positioned in the same plane above the wire, with its top and bottom segments parallel to the wire. The loop is moved vertically upward at a constant speed \\(v\\), directly away from the wire. Which of the following correctly indicates the direction of the induced current in the loop and provides a valid justification based on the magnetic forces exerted on mobile charge carriers?"

# A long, straight horizontal wire carries a steady current \(I\) directed to the right. A rectangular conducting loop is positioned in the same plane above the wire, with its top and bottom segments parallel to the wire. The loop is moved vertically upward at a constant speed \(v\), directly away from the wire. Which of the following correctly indicates the direction of the induced current in the loop and provides a valid justification based on the magnetic forces exerted on mobile charge carriers?

![A long horizontal straight line represents a wire carrying current, with an arrow pointing right labeled I. Positioned directly above the wire in the same plane is a hollow rectangular loop with horizontal length greater than vertical height. A single straight arrow originates from the center of the rectangular loop and points straight upward, labeled \vec{v}. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787461175-QqtTdo.jpg)

- **A.** Counterclockwise, because the rightward magnetic force on positive charge carriers in the bottom segment is greater than the rightward magnetic force on positive charge carriers in the top segment.
- **B.** Clockwise, because the rightward magnetic force on positive charge carriers in the top segment is greater than the rightward magnetic force on positive charge carriers in the bottom segment.
- **C.** Clockwise, because the magnetic force on positive charge carriers is directed upward in the left segment and downward in the right segment.
- **D.** Counterclockwise, because the magnetic force on positive charge carriers is directed to the right in the bottom segment and to the left in the top segment.
