Three single-turn planar wire loops, labeled 1, 2, and 3, each have total electrical resistance \(R\). The loops are pulled to the right at the same constant velocity \(\vec{v}\) across the right-hand boundary of a uniform magnetic field \(\vec{B}\) directed into the page. Loop 1 is a square with side length \(L\). Loop 2 is a rectangle with horizontal length \(L\) and vertical height \(2L\). Loop 3 is a rectangle with horizontal length \(2L\) and vertical height \(L\). At the instant shown, each loop is partially outside the field such that its leading vertical edge is in the field-free region and its trailing vertical edge remains inside the field. Which of the following correctly ranks the magnitude of the external force \(F\) required to keep each loop moving at constant velocity?
