Electromagnetic Induction: Induced EMF in a rotating loop

1. A rectangular loop with surface area A lies in the x,y-plane with two sides parallel to the x-axis and the other two parallel to the y-axis in the presence of a uniform magnetic field with a magnitude B directed along the positive x-axis. The loop is made to rotate around an axis that is parallel to the y-axis and bisects the sides that are parallel to the x-axis with constant angular speed (W). If you assume that at a time t=0, the area vector A is along the positive z-axis (i.e the angle between the area vector and the magnetic field = 90 degrees), determine the induced emf.
