# A rigid rectangular wire loop of width \(w\) and height \(h\) moves in the plane of the page at a constant horizontal velocity \(v\). The loop enters, fully passes through, and then exits a region of width \(4w\) containing a uniform magnetic field \(\vec{B}\) directed perpendicularly into the page. Which of the following correctly pairs the direction of the induced current as the loop enters the field with the direction of the net magnetic force on the loop as it exits the field?

A rigid rectangular wire loop of width \(w\) and height \(h\) moves in the plane of the page at a constant horizontal velocity \(v\).

![A rectangular region in the center is filled with an evenly spaced four-by-four grid of sixteen \times symbols labeled \vec{B}. To the left of this region, a single rectangular wire loop of height h and width w sits entirely in the field-free area. A horizontal arrow labeled v extends from the right edge of the wire loop, pointing horizontally to the right toward the magnetic field region. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596697-e8NXuE.jpg)

- **A.** Induced current: Clockwise; Net magnetic force: Directed to the right
- **B.** Induced current: Clockwise; Net magnetic force: Directed to the left
- **C.** Induced current: Counterclockwise; Net magnetic force: Directed to the left
- **D.** Induced current: Counterclockwise; Net magnetic force: Directed to the right
