Your answer is partially correct. In the figure, a 100-turn coil of radius 3.0 cm and resistance 5.0 Q is coaxial with a solenoid of 200 turns/cm and diameter 4.0 cm. The solenoid current drops from 1.7 A to zero in time interval At = 21 ms. What current is induced in amperes in the coil during At? Coil Solenoid ▬▬▬▬▬ Number i 0.127 A Units
A long solenoid has n = 370 turns per meter and carries a current given by I = 35.0(1 - e-1.60t ), where I is in amperes and t is in seconds. Inside the solenoid and coaxial with it is a coil that has a radius of R = 6.00 cm and consists of a total of N = 250 turns of fine wire (see figure below).
