The figure shows four wire loops, with edge length of either `L` or `2L`. All four loops will move through a region of uniform magnetic field `vecB` (directed out of the 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

A

`(e_(c)=e_(d)) lt (e_(a)=e_(b))`

B

The following figure shows four wire loops, with edge lengths of either Lor 2L. All four loops will move through a region of uniform magnetic field B (directed out of the page) at the same constant velocity. (Corresponding to loop mentioned in Column II, information on induced emf is provided in Column I, match them correctly).

The graph gives the magnitude B(t) of a uniform magnetic field that exists throughout a conducting loop, with the direction of the field perpendicular to the plane of the loop. Rank the five regions of the graph according to the magnitude of the emf induced in the loop, greatest first.
