358468 The figure shows four wire loops, with edge lengths of either \(L\) or \(2L\). All of four loops will move through a region of uniform magnetic field \(\vec{B}\) (directed out of page) at the same constant velocity. Rank the four loops according to the maximum magnitude of the e.m.f. induced as they move through the field, greatest first
