A long solenoid of cross-sectional area 5.0cm25.0cm2 is wound with 25 turns of wire per centimeter. It is placed in the middle of a closely wrapped coil of 10 turns and radius 25 cm, as shown below. (a) What is the emf induced in the coil when the current through the solenoid is decreasing at a rate dI/dt=−0.20A/s?dI/dt=−0.20A/s? (b) What is the electric field induced in the coil?
