A 320 turn solenoid with a length of 19.0 cm and a radius of
1.20 cm carries a current of 1.90 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 320 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 320 turn solenoid....
