A square loop falling vertically through a region of uniform magnetic field.
A square loop falling vertically through a region of uniform magnetic field.
A square wire loop of side length \(L\) and resistance \(R\) is released from rest above a region of uniform magnetic field directed into the page. The height of the magnetic field region is greater than \(L\), and the magnetic force on the loop is negligible compared to gravity as it falls. Counterclockwise current in the loop is defined as positive. Which of the following best describes the graph of the induced current \(I\) in the loop as a function of time \(t\) as it falls completely through the magnetic field region?
