A long solenoid has n=400 turns per meter and carries a current given by:
I=30.0(1-e^(-1.60t))
where I is in amperes and t is in seconds. Inside the solenoid is a coaxial coil with a radius of R=6.00cm and consists of a total of N=250 turns of fine wire.
(a) Determine the emf induced in the coil by the changing current.
