From faradays law of induction
average induced emf = change in flux/time
emf = N*A*B/t
emf = 100*pi*(0.18 m)^2*0.35 T/(0.30 s)
emf = 11.87522023 v
emf =12 v

Figure 25.16 (which looks like a horizontal bar with three rows of little blue arrows pointing in the upwards direction through the bar) shows a 100-turn coil of wire of radius 12cm in a 0.15T magnetic field. The coil is rotated 90 degrees in 0.30 s, ending up parallel to the field. What is the average emf induced in the coil as it rotates?

Can someone help me? Thank you.
Problem 25.62 Part A Experiments to study vision often need to track the movements of a subjects eye. One way of doing so is to have the subject sit in a magnetic field while wearing special contact lenses that have a coil of very fine wire circling the edge. A current is induced in the coil each time the subject rotates his eye. Consider an experiment in which 20 turn, 6.0 a-mm-diameter coil of...
