3. In an experiment to determine the flux density of the region in between the pole pieces of magnet, a 50-turn coil of 40 ohms resistance and area of 2.0 cm² is placed with its plane perpendicular to the field and then quickly withdrawn from the field. The charge flowing in the operation is found to be 5.0x104 coulomb. What is the flux density?
