# A flat, rigid rectangular conducting loop with vertical width \(w = 0.40\text{ m}\) and total resistance \(R = 2.0\text{ }\Omega\) moves at a constant speed \(v = 5.0\text{ m/s}\) directed to the right. The loop is partially immersed in a uniform magnetic field \(B = 1.5\text{ T}\) directed perpendicular to the plane of the loop. What is the magnitude of the net magnetic braking force acting on the loop as it leaves the magnetic field?

![A rectangular region on the left contains a grid of six rows and six columns of cross marks representing a uniform magnetic field \(B\) directed into the page. A single rectangular conducting wire loop lies horizontally in the plane of the page, with its left side inside the magnetic field region and its right side outside the magnetic field region. A single horizontal arrow pointing to the right is attached to the right edge of the loop and labeled \(v\). A double-ended vertical dimension arrow spans the vertical edge of the loop and is labeled \(w\). No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787461196-0AWByW.jpg)
