Q16: A long solenoid has n = turns per meter and car- ries a current given by I = , 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 = cm and consists of a total of N = turns of fine wire (Fig. P31.16). What emf is induced in the coil by the changing current?
t =
pi =
g =
