I have a problem where a 40 turn coil surrounds a a 200 turn solenoid and I am asked to find the maximum induced emf.

Without going into exact details,

to get the EMF do I need to multiply my expression for the change in flux w/ respect to time by 40?

Also, The area in dflux/dt = dB/dt dot A is the cross sectional area of the solenoid, not the coil, correct?

2. Relevant equations
