A coil of 125 turns has an area 6.63 × 10-3m2 and has its plane perpendicular to a 75 X 10-3 T magnetic field produced by a nearby electromagnet. The current in the electromagnet is turned off leading the magnetic field to disappear and causing an average emf of 0.65 V to be induced in the coll. How much time does it take for the field to disappear in units of seconds? Give your answer as a positive number _______
