In the figure shown a long conductor carries constant current `I`. A rod `PQ` of length `l` is in the plane of the rod.The rod is rotated about point `P` with constant angular velocity `omega` as shown in the figure.Find the `e.m.f` induced in the rod in the position shown.Indicate which points is at high potential.
