A ring rotates with angular velocity ω about an axis in the plane of the ring which passes through the center of the ring. A constant magnetic field B exists perpendicualr to the plane of the ring . Find the emf induced in the ring as a function of time.

Figure shows a rectangular loop moving in a uniform magnetic field. Show the electrical equivalence of each branch. what is the net induced emf ?
