A circular loop of wire of radius r = 0.29 m and resistance R = 4.2 Ω lies in a plane perpendicular to a spatially constant magnetic field of initial magnitude B(0) = 5.2 T. If the field is reduced to zero, what is the magnitude of the total charge that moves through the loop. This value of charge is independent of the function B(t) that takes the field to zero. C
