19 - A conducting loop consisting of N coils is rotated
about an axis parallel to the plane of the coils and
through the middle of the loop as shown. The loop
has an area A, and rotates with a constant angular
velocity w in the vicinity of a constant magnetic field
B, which induces a time-varying emf in the coil. What
is the magnitude of this emf as a function of time?
(Faraday's law e = -NE)
