A strong electromagnet produces a uniform magnetic field of 1.60 T over a cross-sectional area of 0.260 m2. A coil having 210 turns and a total resistance of 23.0 %u03A9 is placed around the electromagnet. The current in the electromagnet is then smoothly reduced until it reaches zero in 20.0 ms. What is the current induced in the coil?
