Magnetics

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