A rod of length $\displaystyle 60$ cm rotates with a uniform angular velocity $\displaystyle 20 \mathrm{rad} s^{-1}$ about its perpendicular bisector, in a uniform magnetic filed $\displaystyle 0.5 T$. The direction of magnetic field is parallel to the axis of rotation. The potential difference between the two ends of the rod is $\displaystyle \_\_\_\_$ V.
