The correct answer for the question that is being presented above is this one:

Phi = BAsin(theta)
1. Phi(i) = BA
2. Phi(f) = 0
3. EMF = N(phi(i)-phi(f))/deltat

Here are the follow-up questions:

1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated?
2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated?
3. What is the magnitude of the average emf induced in the coil?
