A 2 m long large coil with a radius of
19.2 cm and 170 turns surrounds a 7.8 m
long solenoid with a radius of 9.2 cm and 4000
turns.
The current in the solenoid changes as
I = I0 sin(2*pi*f*t)
where I0 = 30 A and f = 60 Hz.
Inside solenoid has 4000 turns and putside coil has170 turns.
Find the maximum induced emf E in the
large coil. Answer in units of V.

That looks like something I used to be able to do. Think about Faraday's laws or equations. Don't forget that the back emf acts to oppose the force causing it. Whatever convention you use, stick with it through the entire problem. What I mean is, positive to negative stays that way or negative to positive stays that way. You can't switch between them in the middle of problem solving.
Also consider Maxwell's equations.

I truly have this similar homework and prefer you at the same time as i could not discover the answer I became to the internet! besides using the coaching you acquire and such, the answer I were given replaced into -- up and north are the nonzero elements. desire that permits!
