A 1.0 m long metallic rod is rotated with a frequency of 30 rev/s about an axis perpendicular to the rod passing through its one end. The other end of the rod is in contact with a circular metallic ring. A constant and uniform magnetic field of 0.8 T exists in the region parallel to the axis of rotation. The electromotive force (emf) developed between the center and the ring is:
