# A long, straight horizontal wire carries a current \(I\) to the right that is steadily decreasing in magnitude over time. A stationary rectangular conducting loop is positioned directly above the wire in the same plane, with its bottom edge parallel to the wire, as shown.

Which of the following correctly identifies the direction of the induced current in the loop and the direction of the net magnetic force exerted on the loop by the magnetic field of the straight wire?

![A schematic diagram in the plane of the page showing a long horizontal straight wire in the lower portion and a single rectangular loop positioned in the upper portion. The horizontal wire spans across the bottom region with a single arrow on it pointing to the right labeled \(I\). Directly above the wire, separated by a vertical gap, is a single planar rectangular loop with horizontal top and bottom sides parallel to the straight wire, and vertical left and right sides perpendicular to the wire. The entire loop and wire lie coplanar. No other labels, lines, arrows, or text appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596678-py99Uz.jpg)

- **A.** Induced Current: Clockwise Net Magnetic Force: Directed away from the wire (upward)
- **B.** Induced Current: Clockwise Net Magnetic Force: Directed toward the wire (downward)
- **C.** Induced Current: Counterclockwise Net Magnetic Force: Directed away from the wire (upward)
- **D.** Induced Current: Counterclockwise Net Magnetic Force: Directed toward the wire (downward)
