The wire shown in is bent in the shape of a tent, with θ = 60.0∘ and L = 1.50 m, and placed in a uniform magnetic field of magnitude 0.300T perpendicular to the tabletop. The wire is rigid but hinged at points aandb. If the tent is flattened out on the table in 0.100 s, what is the average induced emf in the wire during this time?

Figure shows a conducting circular loop of radius a placed in a uniform, perpendicular magnetic field B. A thick metal rod OA is pivoted at the centre O. The other end fo the rod touches the loop at A. The centre O and a fixed point C on the loop are connected by a wire OC of resistance R. A force is applied at the middle point of the rod OA perpendicularly so that the rod rotates clockwise at a uniform angular-velocity ω. Suppose the wire connecting O and C has zero resistance but the circular loop has a resistance R uniformly distributed along its length. The rod OA is made to rotate with a uniform angular speed ω as shown in the figure. Find the force.
