A rectangular loop of height h and width w is fixed so that it can rotate about its vertical side. A magnetic field B is constant, uniform, and perpendicular to this vertical axis.
(a) Sketch out the configuration as seen from above.
(b) Calculate the magnetic flux through the loop as a function of its angle to the magnetic field
(c) Imagine that it's now rotating with constant angular speed A%. Write an expression for the magnetic flux as a function of time.
(d) Now, what will the emf around the loop be as a function of time?
(e) If the loop has total resistance R, what will the current be as a function of time?
