(c31p7) In the figure a 140-turn coil of radius 5.00 cm and resistance 2.00 Ω is placed around a smaller diameter solenoid (d = 3.20 cm). The long solenoid in the figure has 230 turns per centimeter and carries a current of 1.40 A. The current in the solenoid is reduced to zero and then increased to -1.40 A in a time of 4.00×10-2 s. What is the magnitude of the induced current in the outer coil while the solenoid current is being changed?

A 310 turn solenoid with a length of 23.0 cm and a radius of 1.60 cm carries a current of 1.85 A. A second coil of four turns is wrapped tightly around this solenoid, so it can be considered to have the same radius as the solenoid. The current in the 310 turn solenoid increases steadily to 5.00 A in 0.900 s. (a) Use Ampere's law to calculate the initial magnetic field in the middle of the 310 turn solenoid....
