A loop of wire of radius a = 35 mm has an electrical resistance R = 0.038 Ω . The loop is initially inside a uniform magnetic field of magnitude B0 = 1.8 T parallel to the loop's axis. The magnetic field is then reduced slowly at a constant rate, which induces a current I = 0.20 A in the loop. How long does it take for the magnitude of the uniform magnetic field to drop from 1.8 T to zero? Find the time Δt it takes the magnetic field to drop to zero.
