The figure below shows a loop of wire of mass m = 0.0251 kg, width L = 0.0537 m, and resistance R = 0.494 Ω dropping out of a region of constant magnetic field of magnitude B = 1.47 T pointing into the page. As long as the top of the loop is in the magnetic field, the equation describing the speed of the loop v is given by mdvdt + vL2 B2 R = mg. Replacing the speed by the current i, this equation has the same form as that for a series RL circuit. What is the speed of the loop after t = 3.58 s?

A circular loop of wire of radius r = 0.124 m and resistance R = 3.44 Ω lies in a plane perpendicular to a spatially constant magnetic field of initial magnitude B(0) = 5.49 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.
