A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w, with the first named corner moving in the az direction at t=0. Assume a uniform magnetic flux density B=B(0)az. Determine the induced emf in the rotating loop and specify the direction of current.
