A conducting circular loop of radius r carries a constant current l. It is placed in a ukniform magnetic field vecB such that vecB is perpendicular to the place of the loop. The magnetic force acting on the loop is

As shown in the figure, a rectangular loop of a conducting wire is moving away with a constant velocity v in a perpendicular direction from a very long straight conductor carrying a steady current I. When the breadth of the rectangular loop is very small compared to its distance from the straight conductor, how does the emf E induced in the loop vary with time t?
