Chapter 21, problem 7.  
 A closely wound rectangular coil of N turns has dimensions of x1 cm by x2 cm. The plane of the coil is rotated from a position where it makes an angle of x3ᵒ with a magnetic field of x4 T to a position perpendicular to the field. The rotation takes x5 s.
What is average emf induced on the coil?
