8- m long rod rotates about an axis through one end and perpendicular to the rod, with an angular speed of 1.9 rev/s.

A 0.8- m long rod rotates about an axis through one end and perpendicular to the rod, with an angular speed of 1.9 rev/s. The plane of rotation of the rod is perpendicular to a uniform magnetic field of 0.8 T. Calculate the emf induced across the ends of the rod.
