A uniform but time varying magnetic field is present in a circular region of radius R. The magnetic field is perpendicular and into the plane of the loop and the magnitude of field is increasing at a constant rate . There is a straight conducting rod of length 2R placed as shown in figure. The magnitude of induced emf across the rod is:
