A rod of length I rotates with a uniform angular velocity
about an axis passing through its middle point but normal to its length in a uniform magnetic field of induction B with its direction parallel to the axis of rotation. The induced emf between the two ends of the rod is

Length of the rod between the axis of rotation and one end of the rod 
Area swept out in one rotation 
Angular velocity 
Frequency of revolution 
Area swept out per second 
Magnetic induction = B
Rate of change of magnetic flux 
Magnitude of induced emf 
Magnitude of induced emf between the axis and the other end is also
these two emf’s are in opposite direction hence the potential difference between the two ends of the rod is zero.
